Introduction In this work, we intend to present which are the available

means of protection and security of personal mobile computer devices, especially against theft and unauthorized use.

Aspects covered:

• General security concepts• General measures of protection for personal devices• Applications for data protection• Mechanisms of anti-theft protection

Personal mobile computer devices

General Security Concepts The Information Security ensures the preservation of certain

properties of the information contained in the different ways in which this can be revealed.

There are basic principles that need to be secured for protection, such as:

Availability Confidentiality

Integrity Authenticity

The loss of any of these characteristics is a threat to information security.

General measures of protection for personal devices

There are simple steps that are within reach for all users of personal devices in order to increasing safety:

• Access control mechanisms such as passwords and firewalls;• Creating backup copies;• Software updates;

Applications for data protection• Data Encryption

The encryption of a message is thus to modify its character, by mathematical operations in order to place the characters in transit clear-cut, and the receiver apply for other mathematical operations can understand.

Symmetric Algorithms Asymmetric Algorithms

Mechanisms of anti-theft protection

The theft of a laptop computer is currently seeing a huge problem when we consider the amount of personal information located in one device

Security problems, are constantly present in the everyday of a user of information technologies.

One solution, to be taken into account, is to guard the safety of sensitive data and encrypt them, requiring a password or a "keyfile" to access such information

Mechanisms of anti-theft protection

• Physical Mechanisms

-Security cable for laptops with anti-theft lock with safety key

- Anti-theft cable with combination and alarm

Mechanisms of anti-theft protection

• Physical Mechanisms

Safety device for usb flash drive

Biometric Readers - authentication through fingerprint

Mechanisms of anti-theft protection

Remote locking / Location systems Nonstop Laptop Guardian
