However, there are quite a few AR-based mobile video communication models today, yet the existing models are limited and insufficient in supporting technical(More)
File similarity is a numerical indicator that how many duplicated data exist in target files. With this information, we can reduce storage capacity with data deduplication scheme, further it can be exploited in the digital forensic field for finding malicious software. However, measuring file similarity between files can cause a high overhead in terms of(More)
A mobile phone supporting a fixed-mobile convergence (FMC) network environment has attracted much interest from customers, because it enables users to access to both wired and wireless network with a single mobile phone. This paper presents loosely-coupled embedded system architecture for an FMC mobile handset. The main idea of the approach is to separate(More)
So far, the data anonymization approaches based on k-anonymity and l-diversity has contributed much to privacy protection from record and attributes linkage attacks. However, the existing solutions are not efficient when applied to multimedia Big Data anonymization. This paper analyzes this problem in detail in terms of the processing time, memory space,(More)
