Legal Issues Related To Cloud Hosting

In South Africa, President Zuma recently signed a Privacy Protection Act into law. Various countries have similar laws in place.

Section 11 of said Act makes it a criminal offence to divulge/make known any personal details, contact information, etc., by any person to a third party. It seems a bit drastic but service providers, retailers, even banks have been selling contact details without consent.

This leaves one in a position where you may end up with a criminal record if you have been using cloud services to synchronize contacts, calendars, tasks, etc., via services such as Google and it gets leaked from there. The recent 145 million exposed accounts at eBay comes to mind.

In a criminal court, the state prosecutor may argue that the "reasonable man" should have foreseen such leaks, based upon the history of successful hacking attempts. It could be argued that the user should have refrained from using cloud services.


The sad thing is that, especially for Linux users, there currently is no local sync alternative, except for those who have the resources to run a server with something like ownCloud. Most users simply have no options as device manufacturers are adamant about pushing everything through the cloud.


I stand corrected on this, but I am almost 100% sure that a legal advisor from New Zealand or Australia voiced a similar concern. It is my hope that someone really develops a user-friendly (read: newbie) solution that can be easily installed and configured, at least for Android devices as this is used by the majority.

How To : Install Dropbox 2.8.2 in Ubuntu/Linux Mint

    When you wish to send images/photos or files to your friend who is residing far away from your location, you would prefer to send them by attaching those files to an email. But, there is a limitation to the maximum size of files those can be attached to an email, which generally is a few MBs. So, when it comes to sharing a large chunk of data, say an entire movie of 1.5GB, you would not be allowed to send it as an email attachment. So, the remedy is 'DropBox'. Just store the data you wish to share with your friends in the Dropbox and you're done.

    With Dropbox, you can not only store or send the documents worldwide, but you can also put the back up data into the Dropbox. Very very useful application available for no cost !

Different Quality Backup Idea

My idea is simple. For media that depends on lossy compression it should be possible to ”patch” the media file with a smaller file of same resolution but a lower quality. The backup file is smaller due to more lossy compression. For this to work on image files the format probably need to loose some dependency on the previous block. One error should not affect the rest of the image. On the blocks you then perform some checks. The idea is then that if you encounter a error in the original big image file then you can patch it with the block of pixels in the smaller backup file. The block in the backup file would be of lower quality but look similar. You probable would not notice that the image has been fixed.

 

For a .jpg photo of 3.3MB I saw that I would only need a 350k version. To keep it simple one could store both versions in the same file as an option. For those who don't make backups I think this would make it easier to recover otherwise lost photos.

 

I hope you found this idea interesting.

 

Tips for Cloud Computing Security

    Shared software, shared resources are integral elements of Cloud Computing, which has become a rage today. It’s being used by companies looking for flexibility and scalability. But there are risks involved that you have to keep in mind while using public, private or hybrid cloud computing options. Security of your vital data is of great importance to you and it should be protected while you get the best benefits of cloud computing services. To make effective use of cloud computing and to ensure that data is transferred online securely, there are certain tips you must follow.
 

Know how your data is protected

    Data encryption and firewall security is crucial and you have to know more about these aspects when you sign up with a service provider. Public cloud SaaS solutions make secure encryption practically mandatory. Cloud computing resources should also have an inbound firewall for security reasons. You might be on a cloud but you still have to have strategies in place in case there is an external attack or hostile activity on the system. Service providers that talk about their security measures openly should be given precedence because it enables you to have your own strategies in order.
