Abstract
Preserving data provacy is a challenging task, especially when long-term storage and fault-tolerance are required. Long-term storage systems based on secret sharing appear as an alternate solution to the traditional technique of data encryption and backup restore. Alouneh et al. (2013) propose such a method, which they claim to be both secure and efficient. We show their assertion is false and exemplify some vulnerabilities of their construction, which arrise natural from the deterministic behavior of their system.
