How To Prevent Thieves From Stealing Your PDF Ebooks!
How To Prevent Thieves From Stealing Your PDF Ebooks!
There are 2 main options for protecting your PDF file: OPTION 1: Use Adobe Acrobat’s basic protection. Adobe Acrobat allows you to set basic protection for your PDF document. This includes: * allow/disable the ability to copy text of document * allow/disable printing of file * allow/disable changing document * require password to open document (Yes their password protection was broken a few years back, but it’s still adequate protection and will keep out most people.) Ideally, to use this option you should use Adobe Acrobat, however the high cost may put that out of reach of many. Fortunately, there are MANY, MANY inexpensive PDF creators that will allow you to also set some of these permissions. Such as: http://www.pdf995.com http://www.pdffactory.com http://www.deskpdf.com There are also some standalone applications like: http://www.verypdf.com/encryptpdf/index.htm Overall, option 1 is what I call “static protection”. Meaning, once you choose the security and then distribute the file, you cannot change the security for those files that are already distributed. For example, you distribute a file to Client A in December. In January, your relations with the client become strained and you no longer want them to have access to your file. Unfortunately, with static protection, you cannot change their access permissions. It is already “set”. Though this option may allow you to prevent copying text within the file, it does NOT prevent a user from copying the entire file and redistributing it to others. Though it may allow you to require a password to access the file, the password can be easily passed around so anyone can have access. So it’s not entirely secure and easily circumvented. If protection of your document is critical, you should boost protection using additional mechanisms. OPTION 2: Use a third party protection system. This option includes systems that offer “real time” control over your document. “Real time” means that you have the ability to change or alter the document security after it has been delivered to the end user. This is what I choose to focus on as it provides the greatest amount of security and post-distribution control. Some just offer basic lock and unlock ability, while others go into more extensive PDF settings that can be altered at any point. Here are some things you should be looking for when evaluating a PDF protection system. 1. Does the system offer complete protection? This the first thing you should look at because if the protection is not up to par, move on! You will never even get to the other points. When evaluating protection features, make sure you check each feature out for yourself and don’t always take the company’s word about protection. Many times I have seen companies advertising certain protection features on their website, but in testing, the product doesn’t seem to do what is claimed. So, always check first. For PDF files, there are some basic areas that any adequate system must protect against. In order to be totally protected, the PDF security system you use MUST: * Prevent saving a copy of file. * Prevent emailing of file and exporting or extracting pages from file * Prevent copying of file from the TEMP folder * Prevent copying file and text to the clipboard * Prevent redistilling of the file * Prevent unlimited, uncontrolled printing of file * Prevent access to file without permission * Watermark all printed pages If any system that you look into does not cover these, I recommend that you move on to something that does. 2. Can you afford it? If the system passes the security test, the next thing you should look at is the cost of the system. Is it within your budget? Can you justify the price of this type of service? Do you buy the entire system and run it on your server, or is it a hosted service that charges you a monthly fee. There are pros and cons of both. If you run the system on your server then you will avoid monthly fees, but these types of systems usually require extensive programming and integration work which can increase your overall costs and take weeks to months before you get up and running. If you choose a third party system that is hosted by another company, you avoid the integration issue as most of these services can get you up and running in minutes to hours. 3. Does the system offer auto-distribution? Does it automatically deliver your document to your customers and clients hands-free? If so, does it integrate with your payment system and/or shopping cart? 4. Is the system flexible? The next thing you should look at is the flexibility. Does it allow you to tweak and modify the security options to fit your unique requirements? The ability to customize things such as program icons, customer download emails, thank you pages, etc. makes a big difference. 5. Is there any customer support? What kind of support and help will you receive when you purchase the product or service? Is their any documentation of all features and uses? What good is having the best system if you don’t know how to use it? 6. Is the Company reliable? Does it protect my data? Is this company reliable? Do you feel that the the company will shut down, thus leaving your documents inaccessible and/or unprotected? Ask them what measures do they provide to ensure that your information remains protected in this event? Do they back up your data? If so, how often? 7. Can you demo the system? Most companies offer a trial or demo period for free or a small fee. You should always try the system out to see it “in action”. Set it up to do exactly what you are looking for and see if it works the way you need. Never sign up or purchase something that you have not yet tested. 8. Other questions? Those are the major criteria, of course there are other things that you may want to consider such as: * What is their cancellation/refund policy? Do they require a contract or can you sign up for a month to month service? * Does their system use Acrobat Reader or another PDF viewer? If they use Acrobat Reader, do they have an Adobe DRM license which is required for all Acrobat reader security systems? * Does it allow you to contact your database of users/clients * Can you export your user database There is a lot to consider when deciding on a PDF protection system. My advice is Do NOT rush into it. Because once you choose a system and start distributing files using that system, you are stuck with it. File Secure Pro is a document protection and delivery system that allows users to securely distribute, monitor and control usage of their intellectual property. learn more at <a href="http://www.protectyourfile.com/" title="http://www.protectyourfile.com/" target="_blank">http://www.protectyourfile.com/</a> If you distribute important information online, File Secure allows you to start protecting your information within minutes.

The Key To Computer Security - Anti Virus Software
In the computer world today it is important to remember that at every second your computer is at risk of being contaminated with an ugly virus. There are many ways your computer may become infected from e-mail viruses to Trojans. These infections can cause damage to your hard drive, attach themselves to your programs, or can even spread to other peoples computers from your e-mail. It is essential to protect your computer from these invasions by using a good anti-virus software program. There are many different types of infections that can invade your computer some of which include viruses, worms, e-mail viruses, and Trojans. A virus can be transmitted from computer to computer by attaching itself to another program. When the program is running the virus is able to infect other programs or documents. Worms are a computer program that copies itself from computer to computer through the use of computer networks. They are often used to invade security holes in software programs. The latest computer invaders are e-mail viruses. An e-mail virus moves around in your e-mail messages and duplicates as it automatically sends itself to people in your address book, which in turn infects their computers in the same way. A Trojan horse invades your computer by pretending to be a program it?s not. When you open the program, the Trojan wreaks havoc on your computer that can cause irreversible damage. In order to protect yourself from such invasion it is very important to make sure your computer is safe. One thing you can do is to run a more secure operating system like UNIX that can protect your computer from traditional viruses. Another option is to buy virus protection software if you are using an unsecured computer. Avoiding programs from unknown sources, disabling floppy disk booting, and making sure that Macro virus protection is enabled, are also things that can further protect you from invasion. The best option for protecting your computer though, is to invest in an anti-virus program. There are many anti-virus programs like Norton antivirus, McAfee, and PcCillin, and some are even free like Avast and AVG. Anti virus programs work by keeping patterns of virus infected files and compares them to the files stored on your computer. If it finds any viruses you are immediately prompted to delete the contaminated file. Make sure to up-date your anti virus software consistently, which can be done through the Internet and most up-dates are free of cost. If you are going to use the computer it is always best to protect yourself and your precious memories from all the dangerous computer infections. When you invest in a good computer and store your information on it, you are setting yourself up for a potential disaster that many viruses can cause. It is essential that you make sure that your computer is always protected by investing in a good anti virus program. Dave Michaels writes on home and computer subjects.

Let Your Drawing Respond Faster in ZWCAD
Processing speed of CAD software is one of the most concerned issues of every user. Fast speed can be achieved directly by either software or hardware upgrade. In case of ordinary PC configuration, how can we further raise the speed even without software update? Here are some tips: 1. If you frequently specify the color or linetype for certain entities instead of using Bylayer or Byblock features, data will increase dramatically in the drawing, and it will take more time to process these data. It is suggested to create adequate and appropriate layers to which entities of different meanings or properties can be assigned respectively, so that the option of Bylayer and Byblock can help to reduce the amount of data stored. 2. If there are lots of layers in a drawing, some of which contain complicated entities seldom used, then you can freeze these layers, so that they would not regenerate with other layers, and result in processing time saving. 3. Hatch (Fill) is a kind of entity occupying much RAM. Too much hatches would significantly drag down the processing speed. To maintain high speed: (1) Do the hatching at the last step, so that there are no hatches affecting the speed during previous drafting steps. (2) Assign all hatches to a single or some specific layers and freeze some or all of them if possible. Then they will not regenerate with other entities. (3) In the Config dialogue box, select the Display tab and check the option Not display hatch while zooming. Entities such as Solid, Donut and Trace have another kind of fill. They can be displayed faster by setting OFF for FILLMODE. 4. Text also has influence on the speed of ZOOM, REDRAW and REGEN. Simplifying the display mode of text could help to increase the speed to a large extent. (1) Use a simple text font during the preliminary drafting work, and then replace this font with desired ones at the final stage when there are no more modifications to other graphic entities. (2) Use QTEXT to enable quick display of text. After the command is activated, boundary frames of text areas are displayed instead of text themselves. 5. In the case that we have to insert raster images: (1) Go to the Config dialogue box, select the Display tab and check the option Pan and zoom with raster & OLE, if it is not necessary to view raster images while doing PAN and ZOOM. (2) Use the command IMAGEQUALITY to choose a low quality display mode, when we don’t need to view images with high quality. 6. When REGENMODE is set as ON, ZWCAD will regenerate graphics automatically after executing some commands. Turning the mode off can help to save the time spent on automatic regeneration of graphics. 7. Entities often turn into dash line type for the purpose of highlighting when they are selected for modification. Sometimes such highlights take lots of time to display. So you can think of closing HIGHLIGHT if necessary. Not all methods might suit each specific case, but they do help if applied properly. When you get familiar with these features, drafting work could never be a difficulty in terms of speed, and you may find it easy and convenient to use ZWCAD in any situations.
