Privacy protection is one of key challenges in cloud storage platform. The most popular cloud storage platforms provide good storage services while the privacy information protection is rarely referred. A novel cloud storage architecture with privacy protection is proposed. The privacy information is encrypted using symmetric encryption algorithm with encryption keys which are generated from an encryption tree. And then the secret keys are encrypted using public key cryptosystem to send them to receivers. Receivers are able to decrypt the privacy information correctly. However, the cloud storage provider and any illegal users cannot read the privacy information. The analysis show that the proposed system protect privacy efficiently with no extra storage consumptions.
