2. 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

3. Personal mobile computer devices

4. 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.

5. 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;

6. 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

7. Applications for data protection Data encryption applications  TrueCrypt  Camouflage  Conceal  AxCrypt  Encryptonclick

8. 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

9. 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

10. Mechanisms of anti-theft protection Physical Mechanisms Safety device for usb flash drive Biometric Readers - authentication through fingerprint

11. Mechanisms of anti-theft protection Remote locking / Location systems  Nonstop Laptop Guardian  Safe4cam SNAKING
