Why Passwords Do Not Work and an Alternative Approach to Protecting PDF Files



As far as most people know, using a password is the only way to protect anything and everything on electronic devices, including all documents and files.

Of course, using passwords offers all sorts of advantages, such as the following:

Passwords are readily available – Just about every other PDF manipulation software available can create and enforce passwords for your documents. Such passwords include both document access passwords and permissions passwords, as you will find with Adobe Acrobat. With such measures being so easily available, you will find that most people do not even bother to find out if there are any other measures that they can employ. They are simply content with using whatever is available. And, unless they experience a security breach, they might spend the rest of their lives in blissful ignorance, thinking that the measures they employed are working.

They are convenient and easy to use – How many times does the average individual create a password in their lifetime? From passwords to log in to their computers, emails, social media accounts, and even mobile phones, most people have created a password before. And, creating another password should not present a problem. This ease of use may give individuals more reason to sway to password protection.

The above benefits are all well and good if you only plan on keeping the documents to yourself. If you ever need to share your files, you will open yourself up to a whole bevy of pitfalls that come with password protection. The following are examples of such problems:

The sharing process – If you send a password-protected document to a colleague, you will have to send the password as well. And, the transfer process must be secure for sensitive documents. Yet, emails may not be reliable enough and so you will have to think of other ways that cannot be intercepted. This adds another task to your to-do list. Even if you do think of a smart way to transmit the password, it does not guarantee that no one will get to it before it reaches the intended recipient.

The recipient – Most people will only show you the side of their characters that they want you to see. As such, trusting people can be disastrous when it comes to sensitive documents as the same people may end up disappointing you. For example, what makes you think that the recipient of your password and document will not also share the same with another individual. In fact, the recipient may even decide to remove the protection you set up and you will never know about it. The same holds true for permissions password that many people use to regulate how a recipient can use a document. Removing such a password is a walk in the park in today’s digital world.

Password management – Everybody can agree that using the same password for all your documents could be disastrous. Yet, coming up with 200 passwords for 200 different documents would be taxing. Also, some issues can come when creating a password for each document. Where do you store all the passwords? What happens when users forget theirs? How do you share the passwords? How do you match a password to a particular document? A simple mix up could lock everybody out from using the documents.

Password removal tools – Have you ever Googled password removal tools? You should. You will suddenly realize that your documents are much less safe than you believe after having gone through the search results. Bear in mind that some of these tools are very effective at what they claim to do.

As you have seen, passwords constitute a significant part of the problem in document security. So, how can you protect your PDFs without using passwords?  You should use DRM with public key technology.

Imagine if no one ever had to deal with passwords again.  That reality is here as DRM systems using public key technology transmit keys directly to the user’s computer, without the user knowing what the key is.  Not even the administrator will know what the key is.  So, neither of them can share the key.

In addition, the key locks to an authorized device and so the issue of password sharing will soon be a thing of the past.

There are other features that make the use of a DRM system using public key technology a better alternative to using passwords. These include the following:


Document use control – Controlling details, such as printing permissions and the number of views allowed for each document, are all possible with DRM. This is done persistently and access can be revoked at any time at the admin’s discretion. Also, document modification and the use of any copying features are disallowed, leaving only the secured authorized copy available.

Document use logging – It is hard not to notice weird use behaviours when you are continually monitoring how authorized parties use your documents. So, this could help prevent document theft as it will raise red flags early.

Additional security features – A dynamic watermark displaying user information is a serious thing for document thieves. After all, their identity will forever be linked to the theft. So, this added feature will have them thinking twice about their actions and the potential consequences. That should be beneficial to your document security.

 You should at least take some time to consider the two security options. Chances are that you need an upgrade and even though it might be expensive initially, the move to a DRM system should prove worthwhile in the long run. Do not delay and do not gamble with the security of any of your sensitive documents.

How to Choose the Best Noise Cancelling Earbuds



Noise-canceling earbuds are designed to tune out all the unwanted noise in your environment so that you can enjoy your music. These earbuds are always handy on the daily commute, especially for people who want to drown out the noise on the subway or on traffic. 

But that’s not all. The earbuds also make music sound way better. There are so many different earbuds that cancel noise available right now. Knowing which ones to go for may be harder than you think, but don’t worry. In this guide, we are going to help you pick the most ideal product.

How Do Noise Cancelling Earbuds Work?

Before we give you a guide on how to pick out a good pair of noise-canceling earbuds, it is important too, first of all, explain how these gadgets work. As the name suggests, noise-canceling earbuds are supposed to cancel environmental noise. However, these gadgets achieve this in two ways. First, the earbuds will prevent environmental noise from reaching your ear. They are designed to perfectly fit inside the ear, creating a tight seal that prevents any noise from entering. This process is called passive noise cancellation.  

Secondly, noise cancellation earbuds may also utilize additional technology to get rid of any ambient noise. The gadgets come with inbuilt microphones that detect and analyze environmental noise. The microphone then develops anti-noise frequencies, which are in turn mixed up with the playback in your music. This process is often referred to as active noise cancellation and will effectively drown out any noise that somehow manages to bypass the airtight earplugs.

What to Look For Before Buying Noise Cancelling Earbuds 

Picking the right noise cancellation earbuds will determine the kind of experience you have with these gadgets. You may want to take your time and peruse through some of the brands available before making the final choice. Here are a few factors to look out for as you begin shopping;

1. Wireless vs. Wired 

It’s safe to say that wireless noise cancelling earbuds are very popular with most people. They are also probably the best choice over wired earbuds since they are far more convenient and easy to use. Despite this, wireless earbuds will cost relatively more.  So, if you don’t mind the little discomfort that comes with wires, you can save yourself some money by picking wired earplugs. However, if you are looking for a truly excellent experience, going for wireless earbuds is highly advised. Even if it means spending a few extra bucks, they are worth it.

2. Sound Quality 

Noise-cancelling earbuds are not just supposed to cancel ambient noise. They should also come with proper sound quality that allows you to enjoy your music in a clear sound. The sound quality will vary depending on the earbuds you are using. You should, therefore, decide what type of sound you’d prefer.  For instance, are you one of those people who enjoy warm and well-rounded sound? Or perhaps you’d prefer the intimacy of classical sounds with ultra-high fidelity? Whichever choice you decide, always go for earbuds that can deliver the perfect sound.

3. Comfort 

You may be wearing noise-canceling earbuds for a very long period of your day. The last thing you want is something that feels uncomfortable.  The comfort of earbuds is determined by many factors. 

First, you may want to make sure the gadgets fit perfectly into your ears. If they are too small or too big, they may cause unnecessary discomfort. The sound quality may also have an effect on comfort. Naturally, you want earbuds that offer excellent volume control features so that you can pick just the right amount of sound.  It may also be a good idea to go for breathable earplugs, especially if you are going to be wearing them for a long time.

4. Battery Life

Battery life applies only to wireless earplugs. Each noise cancelling earbud will have a battery life rating. The rating is often denoted in terms of the hours the gadgets can work on a full charge. For example, most standard units on the market can offer up to 20 hours of noise cancellation when fully charged. This essentially means they will last for the entire day.  A good rule would be to select noise cancelling earbuds that offer the longest battery life. However, something that offers more than 20 hours of noise cancellation on a full charge should do.

5. Price 

Price is probably the last thing you should consider when buying noise cancelling earbuds but it’s still very important. After all, you can only buy something you can afford. The cost of earphones is generally determined by the kind of features they have. High-end brands with more advanced features will cost relatively more. The most important thing is to decide how much you want to spend and pick earbuds that fall within that budget. However, do not settle for low quality just because you don’t want to spend extra. 

6. Design

Finally, noise cancellation earbuds should also feature a sleek design that appeals to your overall style. These earbuds are not just here to cancel ambient noise. They can also be a great fashion accessory. Picking something that looks stylish is therefore recommended.

Final Thoughts

Noise cancellation earbuds can be a lifesaver for people who deal with lots of environmental noise on a day to day basis. However, with the massive variety of brands available in the market, it is important to take your time and pick earplugs that actually work for you.  While the factors above should help you narrow down your search, don’t forget to pay attention to any extra features the products may have. For example, earbuds that have a high-quality microphone can be very handy when you need to answer a phone call in the middle of your commute. The charging time too is another important feature. Ideally, you want earbuds that take as little time to charge as possible. Finally, check the weight specifications of earbuds before buying and pick the lightest product you can find.
