Want a digital format of the hard copy of any document? OCR (Optical Character Recognition) technology can be the right option. Changes are taking place in the field of Data Entry service with the improvement of modern technology. Apparently, you may think OCR service as a substitute of data entry service, however, OCR services come with both advantages and disadvantages.

Overview of OCR

Optical Character Recognition is a modern technology for digital replication. OCR technology comes with software, hardware and an additional circuit in the computer to execute conversion process. OCR software can not only read the fonts but also recognize line breaks in a document. The process of OCR is quite simple and easy to manage. The entire process of converting hard copy of a document into electronic document may take only a few seconds.

Advantages of OCR

If you are looking for only converting any document into editable digital format then there is nothing better than OCR services. Optical Character Recognition process saves the time and effort of developing a digital replica of any document. No need to type characters manually on a digital file. Just place the hard copy of the document inside a scanner and get the digital format of that document with the help of OCR software.

With OCR process you can convert a document in several electronic formats like – Microsoft Word, Excel, HTML, PDF, Text or Rich Text formats.

Documents, which are converted through OCR process, are editable and allow the user to modify the content. Compared to manual data entry service the cost of OCR service is quite less for developing electronic replica of any document. OCR service proved better than data entry service for the organizations, which are engaged in developing electronic copy of printed books.

Disadvantages of OCR Service

There are several disadvantages of OCR service regarding the cost as well as the process of recognizing the characters. Initially, the cost of developing replica through OCR process may seem lucrative but if you consider the cost of entire OCR system life cycle, the cost will be much higher than data entry service. Correcting OCR errors counts more cost than preparing a digital format of the document.

High accuracy OCR software can read more than 400 characters/second, approximately, and generates less number of OCR errors compared to any ordinary OCR software. Therefore, if you are looking for OCR process you have to maintain a separate workstation for correcting OCR errors.

OCR software is not efficient in recognizing the handwriting and the fonts, which are quite similar to handwriting. In such cases manual typing plays better role than OCR process.

How efficient is Data Entry Service than OCR?

Compared to ordinary OCR process, conversion life cycle cost is less in data entry service and it provides complete flexibility to data entry operators preparing digital documents from multiple formats like hard copy or audio files. Consider the service of medical transcription where you need to prepare digital documents from audio files. OCR cannot prepare digital document by scanning any audio files. In such services, data entry can prove better than OCR.

It has been found that for services like mailing list conversion or data extraction from the Internet, manual data entry services are still widely accepted across the industry. Data entry service comes with several levels – staring from inserting raw data in a document to an error free document. OCR is efficient during the initial level of data entry service but cannot be a substitute of data entry service. However, the selection of a right service (Data Entry or OCR) depends on requirements of the job.

Before we learn about anti-spam software, we need to first know what is spam. To put it succinctly, spam is unsolicited and unwanted email. Other names for spam are Unsolicited Bulk Mail, Excessive Multi-Posting, and Unsolicited Commercial email, in addition to the more common - spam mail, bulk email or just junk mail. The advent of email brought in an era of instant communication, where information reaches our desktops, at negligible cost, and in no time at all, from across the globe.

Along with the benefits, came the negative aspects of email. For the multitudes of marketing hawks out there, this was an opportunity to send unsolicited promotions of their products, instantly, and at a very low cost. Today, spam has reached such monumental proportions that 10 out of every 13 emails (76.9%) we receive are spam, one way or the other. This is why anti-Spam filter has become a must have software for almost all PC users.


Stopping Spam

Simply put, anti-spam software helps detect spam. It is a software program that detects unsolicited and unwanted e-mail, and prevents them from reaching your inbox.

Anti-Spam software is also known by many different names, such as: Spam Filters, Email Spam Filtering, Spam Blocking Software, Anti-Spam Filter, Spam Filtering Software, Spam Blockers, Bayesian Filters, and Anti-Spam, among many others.

Anti-spam software is installed in your machine to divert the spam coming in. If installed in the mail server, you will never receive the spam, to begin with. The filtering is configured based on a number of criteria. These could be specific words in the subject line, in the body of the message, and the type of attachments accompanying the mail. You could arrange to filter out even the sender’s email address. Certain Internet Service Providers (ISPs) maintain a blacklist of habitual spam senders – known as spammers. Anti-spam software detects these blacklisted senders and rejects them per se.

Over time, anti-Spam software has become sophisticated to match with the wiles of the spammers. They use techniques that do not trash genuine emails by effectively analyzing the content of the email. Such software looks for keywords and tries to interpret their meanings in the sentences. Certain spam filters do not accept emails that come to you in the form of "Undisclosed Recipients." They accept emails where your email address is in the “to” or “cc” fields.

Anti-spam software has become an essential part of your computer’s security, to ensure that you only receive the emails you want, and not others. To help eliminate spam, look for anti-spam software that has the following features, among many others:

Blocking emails using both lists and preset filters - blocks specific addresses, watches subject lines, and messages within

Updating filters automatically Isolates spam outside of your inbox

Puts acceptable emails automatically into your safe list

Monitors and filters multiple email accounts

Now that you know the basics about the need and importance of anti-Spam filter, select the right one for your computer and get rid of the menace of Spam.

Under some conditions(apparently net lag or maybe even my PC lagging) and some practice, I've dugg stories 20+ times . If you refresh, it stays so it's not just the flash being messed up. I've made a simple video showing this. Apparently “flood-clicking” works. This could explain some of the spam. Digg this up! We have the right to know!

Spam will continue spreading as far as it makes profit. If nobody buys from spammers or acts upon their scams, spam will end. This is the obvious and easiest way to fight spam. You can ignore and delete spam emails you receive. But you can also take vengeance on the spammer by complaining to the spammer's Internet Service Provider (ISP). The ISP will block their connection and maybe impose a fine (depending on the ISP's acceptable usage policy). Spammers beware of such complaints and try to disguise their messages. That's why finding the right ISP is not always easy.

Let’s look inside a spam message. Every email message includes two parts, the body and the header. The body is the actual message text and attachments. The header is a kind of the envelope of the message. The header shows the address of the message sender, the address of the message recipient, the message subject and other information. Email programs usually display these header fields:

From: shows the sender's name and email address.
To: shows the recipient's name and email address.
Date: shows the date when the message was sent.
Subject: shows the message subject.

The From: field usually contains the sender's email address. This lets you know who sent the message and allows you easily reply. Spammers, of course, don’t want you to reply and don’t want you to know who they are. Therefore, they put forged email addresses into the From: lines of their emails. So the From: field won’t help you if you want to determine where the spam email comes from.

Tip! With G-Lock SpamCombat you can easily preview not only the message text but also all the fields of the message header . You can choose the preview format by yourself. You can view the message as HTML, decoded message, or message source.There are also several Received: fields in the header of every message. Email programs don’t usually display the Received: lines but the Received: lines can be very helpful in tracing the spam origin.

Just like a postal letter goes through a number of post offices before it’s delivered to the recipient, an email message is processed by several mail servers. Each mail server adds a line to the message header – a Received: line – which contains

- the server name and IP address of the machine the server received the message from and
- the name of the mail server itself.

Each Received: line is inserted at the top of the message header. If we want to reproduce the message’s path from sender to recipient, we start from the topmost Received: line and walk down until the last one, which is where the email originated.

Just like the From: field the Received: lines may contain forged information to fool those who would want to trace the spammer. Because every mail server inserts the Received: line at the top of the header, we start the analysis from the top.

The Received: lines forged by spammers usually look like normal Received: fields. We can hardly tell whether the Received: line is forged or not at first sight. We should analyze all the Received: lines chain to find out a forged Received: field.

As we mentioned above, every mail server registers not only its name but also the IP address of the machine it got the message from. We simply need to look what name a server puts and what the next server in the chain says. If the servers don’t match, the earlier Received: line is forged.

The origin of the email is what the server immediately after the forged Received: line says about where it received the message from.

Let's see how determining of the spam email origin works in real life. Here is the header of a spam message we’ve recently received:


**************************************************
Return-Path:
Delivered-To: press@mydomain.com
Received: from unknown (HELO 60.17.139.96) (221.200.13.158) by mail1.myserver.xx with SMTP; 7 Nov 2006 10:54:16 -0000
Received: from 164.145.240.209 by 60.17.139.96; Tue, 07 Nov 2006 05:53:35 -0500
Date: Tue, 07 Nov 2006 12:48:35 +0200
From: Pharmacy
Reply-To: umceqhzjmndfy
X-Priority: 3 (Normal)
Message-ID:
To: press@mydomain.com
Subject: Cheap Med*s V!agra Many Med_s QnNXpRy9 MIME-Version: 1.0
Content-Type: text/html; charset=us-ascii
Content-Transfer-Encoding: quoted-printable
**************************************************

At first, look at the forged From: field. The email address in the From: and Reply-To: lines doesn’t exist. So, the spammer took care about directing bounced messages and all the indignant replies people may send to a non-existing email account.

Secondly, the Subject: line. It contains the variations of the “Meds” and “Viagra” words that are known to be met in spam messages. Plus, the subject contains a range of random characters. It’s obvious that the subject line is skillfully tailored to fool anti-spam filters.



Lastly, let’s analyze the Received: lines. We start from the oldest one - Received: from 164.145.240.209 by 60.17.139.96; Tue, 07 Nov 2006 05:53:35 -0500. There are two IP addresses in it: 60.17.139.96 says it received the message from 164.145.240.209.

We check if the next (and last in this case) mail server in the chain confirms the state of the first Received: line. In the second Received: field we have: Received: from unknown (HELO 60.17.139.96) (221.200.13.158) by mail1.myserver.xx with SMTP; 7 Nov 2006 10:54:16 -0000. mail1.myserver.xx is our server and we can trust it. It received the message from an "unknown" host, which says it has the IP address 60.17.139.96. Yes, this confirms what the previous Received: line says.

Now let’s find out where our mail server got the message from. For this purpose, we look at the IP address in brackets before the server name mail1.myserver.xx. It is 221.200.13.15. This is the IP address the connection was established from, and it is not 60.17.139.96. The spam message originates from 221.200.13.15. It’s important to note that it’s not necessarily that the spammer is sitting at the computer 221.200.13.15 and sending spam over the world. It may happen the computer’s owner doesn’t even suspect of being sending spam. The computer may be hijacked by a Trojan, which is spreading spam without the machine’s owner knowing it.


We hope this information will help you identify the spammer's ISP and report them about spam so they can take proper measures.

It is believed that on an average, an email user receives more than 2000 Spam emails every year! By certain accounts, an email user receives more than 77 percent of the mail as spam – which is around 10 out of every 13 emails you receive! More than two-thirds of the email passing through the air waves are pure junk – unwanted and unsolicited. It, therefore, becomes imperative that you chose the right anti-spam software that meets with your requirements.

Spam happens to be one of the biggest disadvantages of using communication channels through the Internet. There is every need to find ways to separate the wanted emails from the unwanted and unsolicited ones. Choosing the correct anti-spam software or Spam filter is the right way to cut down on the spam you receive.

Handling Spam

The amount of spam you can detect and delete depends on the type of screening your emails go through. Many anti-spam software have a multi-level of email screening, which is worth the money you spend. You can even select a trail version or free anti Spam software to sample what it does and then you can opt for a full version with enhanced features and full functionality.

One of the best places to trap and eliminate spam is at the servers that receive, forward, and send the emails. You, of course, have no control over the type of anti-spam handling done by your Internet Service Provider (ISP). To handle spam, there are particular services available to filter them. For a nominal amount each month, a particular service inspects and cleans your inbox. Another service involves forwarding your complete inbox to their servers, where the clean up occurs as emails arrive.

As personal spam blockers, a number of anti-spam software are available from reputed anti-spam suppliers, such as Symantec, McAfee, eScan, PC Mantra etc to name a few. Such software capture and inspect all emails coming in before allowing the clean ones into your inbox.

The type of anti-spam software you select will depend on the volume of emails you handle. It will also depend on the budget you allot to the anti-spam program. The best anti-spam software for you should have the following features, among many others:

It should allow you to see who the sender of the email is, the subject, and the attachment. You can then decide whether to delete the email or accept it.

A chance to preview the message before downloading it. This will enable you to delete if you do not like the message.

The feature that allows you to bounce back the spam email is a great way to let the sender think that your email address is no longer valid. This would probably make them remove you from their mailing list!

There are a number of anti-spam software available with a number of online suppliers that you need to explore, to select the best that is suitable for your needs.
