Abstract: Security of communications between users involving mobile devices has to date focused to ensuring message integrity, preventing attacks as well as verification/authentication of the user to access the message. At the same time manufacturers of LCD displays for use within electronic devices, particularly mobile devices have focused to extending the viewing angle of these displays, their brightness and contrast. As a result, content that has been securely encrypted, delivered, and decrypted is visible to malevolent individuals or organizations around the user when accessing this content. As such secure information, credentials, etc may be divulged without the user being aware. Accordingly, the invention acts to limit the external viewing angle of LCD displays allowing reduced breaches of confidential information. Embodiments of the invention can be integrated with the LCD displays during manufacturing, added to the mobile device in assembly or form part of an after-sales option.
