Background. A significant part of data stored in cloud storages is multimedia data. The procedure of data protection can be organized as a trusted cloud service. Since this service is an intermediate layer between user layer and cloud storage the time of data processing in it is a critical matter. To achieve decreasing of time required for data protection procedure, parallel computations can be employed.
Objective. The objective of the research is to evaluate and analyze the time efficiency of parallel computations fulfilling in multimedia data protection procedures.
Methods. The comparative analysis results for three methods, namely: data fragmentation method, complementary image method, and LSB-based method with AES encryption, are presented in the paper. The methods are considered in terms of data processing time efficiency. The impact of both stegobits used for data embedding and data parallel processing threads is analyzed. The comparison is carried out for two types of multimedia data – audio data and graphical data.
Results. The time efficiency characteristics obtained and analyzed in the research show that the use of parallel computations in the Complementary Image method enables the decreasing of data processing time up to 70%.
Conclusions. The presented results enable comparing the considered methods in terms of their realization as software tool that is, along with data protection level, important characteristic for cloud services user. The Complementary Image method with parallel data processing can be effectively used for multimedia data protection.
