How to protect a pdf file?

A PDF file can be protected in many ways. Some methods are most secure while others can be superficial.

The first choice for most people will be the use of Adobe's own solution known as Acrobat. With Adobe Acrobat a PDF can be protected using password and/or expiration. There are many other PDF creators that also offer password and expiry date protection and the user needs to beware of imitations because many PDF converters do not properly protect the PDF. To enforce any limitations on a document it needs to be encrypted to prevent normal viewers from ignoring the protection. So when it comes to general distribution most authors will want to use Adobe tools because they are more widely used.

But if your document requires bullet-proof protection you need to look at a more secure solution, one that your users cannot use other software to remove the protection. PDF protection and DRM are popular targets by nuisance developers and one only has to perform a web serach on "remove protection from PDF" to realise just how many apps are available for removing PDF protection and just how exploitable these so called "protect" solutions really are.

To further protect PDF an author may also want to prevent unauthorised sharing. Here DRM can be used to ensure that only the author assigned users can open a document. But as with password protection DRM can also be exploited, that is, unless you use a document solution that is designed for protection from end to end. Copysafe PDF is such a solution and by using its proprietary reader with DRM options you can distribute PDF documents by email, download and on disk with the most secure and unexploitable protection from all copy including screen capture.

How many pixels in HD?

There are several different formats of HD. The one used most widely is 1080 x 1920. Multiply the number of lines by the number of pixels per line and you get 2073600 pixels per frame. Each pixel requires 3 bytes to display 24 bit colour so there are 6220800 bytes per frame. (broadcast equipment uses more bits per pixel). Note that the number of pixels is per frame, so a 1080i (interlaced) image will have the same number of pixels but will use two separate fields to display them. Finally, as there are 29.97 frames per second (US standard) a full HD image will need around 186 megabytes per second for full quality moving video.

Can a human destroy a Dalek?

Daleks are not invulnerable. The right kind of weaponry can destroy them easily, it's just they tend to be in too great a number in places where such weaponry is available, and in places where no such weapons exist when they are in smaller numbers.

So a human with such a weapon is capable of destroying a Dalek. Jack Harness does, so does Rose Tyler, Jackie Tyler and Mickey Smith.

How do you Design a unique website and provide perfect designing services in India?

Having a website and taking your business online are two different things. Where we follow a blind approach and just build a website and some social media pages and start believing that “wow” my business is now online.

But is that really so?

“Like each business is different, each customer is different so should the digital strategy be different for each of them. Just some template or a copy-paste approach doesn’t help. Do you agree?”

When we do an offline business each of us has a different way of connecting with our clients/customers. Even though in the same industry we have our own customized way of doing our business but that doesn’t always reflect in how we have built our website or have setup our digital presence.

Your website or your social media should be a reflection of what and how you actually run your business and not a templated way of how businesses are run. I do agree that business do have a lot of things in common, but it’s the uniqueness in very business that sells. It’s that difference that gets us our set of clients and customers.

So we need to really answer a few questions when we see our website or our current social media :

  1. Is my business website truly my website or a generally templated website?

  2. Is my business website unique and reflects the true me and my business?

  3. Do my clients get that personalised feeling just the same way as they have personally met me?

This becomes all the more important when today most of the businesses are being searched online and people not getting opportunities to meet in person. It would be this digital presence that would be talking about you. So make sure your website and your social media speaks about you and not somebody else.
