ENCRYPTION AND DECRYPTION OF DATA IN A CLOUD STORAGE BASED ON INDICATIONS IN METADATA

摘要

Provided are a method, a system, and a computer program product in which metadata associated with encrypted data is maintained in a cloud computing environment, wherein the metadata indicates whether reading of information in the encrypted data is restricted geographically. A controller provides a decryption code for decrypting the encrypted data to a cloud server located in a geographical location, based on whether the metadata indicates whether the reading of information in the encrypted data is restricted geographically.
