An enhanced integrity of web contents through mobile cloud environments

As digital information becomes more pervasive, the threat to the integrity of the data increases. The proliferation of electronic services, e.g., Internet shopping, Internet banking, e-learning, has changed in many aspects of daily lives. Clearly, there are a lot of demands for an efficient authentication system that will guarantee the integrity of the electronic content from a trusted source to a client, especially when it is distributed and aggregated through third parties. Web content can be complex to authenticate. A website is made up of many parts (html, stylesheets, javascripts, etc.). The main focus in this paper is authentication of web content. The web contents have features certainly seem to have escalated in frequency. Web data cover a variety of platforms, metadata and file types, so electronic authentication of web contents must take care to choose a method that collects the content and data required for authentication. Just time stamp and a hash value are not enough for authenticating web contents. To resolve the authentication problem of electronics contents, we present a authentication approach for a snapshot of web contents on PC or mobile devices. This technology leverages a secure authentication by extraction of the feature values from image, then we make use of MD5 for data integrity and public key cryptosystem for digital signature. This approach enables us to verify data integrity for a snapshot of web content.
