<p>The present invention relates to a system and a method for managing data safely in a public cloud environment, which transmit, to a user terminal, authentication information generated in response to the user terminal′s request for access to a public cloud network; allow the user terminal to connect to authentication information and user information in the public cloud network, to generate a user authentication value through hash function calculation, and to transmit the generated user authentication value to the public cloud network; confirm the authentication information in the public cloud network included in the user authentication value on the public cloud network to accept service approval; check whether the data to be uploaded is normal by analyzing the data while confirming whether the user is legitimate by comparing the user authentication values with each other on the public cloud network, when the user terminal connects a user authentication value to data to be uploaded and transmits the data to the public cloud network; and proceed with upload only when the data to be uploaded is normal. According to the present invention, the system and method receive authentication information from the public cloud network to verify a member, generate a user authentication value based on received server authentication information, and store data together with the generated user authentication value to protect the data, thereby blocking a user′s access, who is not identified, preventing the storage of malicious data in a cloud storage, and additionally improving the reliability of a public cloud storage by making clear the source of the data.</p> |
