V⊕SEE: Video secret sharing encryption technique
Piyushi Manupriya, Shambhavi Sinha, Krishan Kumar · 2017
In this digital world, multimedia content is increasing exponentially. Videos occupy the core of this multimedia data. Today, application of videos can be found in almost every field of security surveillance, traffic supervision, weather monitoring, video conferences, social media, etc. Storage and transmission of this data have thus become a prime concern, keeping security and privacy aspects in mind. In order to address the above issue, a new algorithm has been put forward in this paper based on Multi-Secret Sharing scheme along with temporal reordering of frames. Cryptography involving traditional encryption algorithms like DES and AES are found computationally infeasible in real time due to use of Block Ciphers where 128-bit data is broken into blocks. Same transformation is applied to each block and later re-combined resulting expensive to use. However, the V⊕SEE encryption process requires less bandwidth and computational power as compared to AES and DES. As the number of wireless devices being used today which have limited bandwidth and computational power, the algorithm is designed for efficient computation with limited resources. The qualitative and quantitative evaluation is performed in order to compare the performance of the proposed model, existing models and state-of-the-art models. A computing analysis indicates that the proposed approach can meet the requirement of real-time applications.
