Data protection impact assessment system in the mode of risk management by Ying CHENG

“…In the era of big data,the risk management approach has been broadly applied in the field of personal information protection.Data protection impact assessment has become an important system to promote data protection.It takes the provisions of the data protection impact assessment of the European General Data Protection Regulation (GDPR) 2016 as the sample.By using the literature research and empirical analysis method,it analyzes in depth the theoretical background,rise and evolution,meaning and scope of data protection impact assessment to establish a standardized and specific impact assessment system as well as promote personal information protection.Assessment content includes not only privacy risk assessment,but also data security,data quality and non-discrimination.Data protection impact assessment should be set as a mandatory obligation for data processing activities that are likely to result in high risks.The evaluation process shall take the advices from stakeholders to reflect their benefits.The external supervision should be strengthened and the assessment report shall be published properly.…”

Multi-authority attribute hidden for electronic medical record sharing scheme based on blockchain by Lin JIN, Youliang TIAN

“…Currently, there is no data exchanging and sharing between different hospitals, and it is easy to form data islands.At the same time, regional medical data contains a large amount of sensitive information of patients.The public acquisition, sharing and circulation of these data will lead to malicious tampering, theft, abuse and loss of ownership, thereby revealing patient privacy.In addition, the size of medical data is enormous and the data is unstructured, then it is more difficult to prevent and hold accountable some highly targeted malicious attacks, such as malicious attacks on medical data theft, tampering, and extortion.In view of the above problems, a blockchain-based on multi-authority attribute hidden electronic medical record sharing scheme was proposed to achieve fine-grained access to shared electronic medical records while ensuring patient privacy.The Multi-Authorization Attribute Encryption (MA-ABE) algorithm was introduced, which used multi-authority organizations to manage decentralized attributes.It also used hash functions to identify different users, in order to effectively resist collusion attacks between users with different authorizations.Besides, the linear secrets sharing scheme (LSSS) was used to realize partial hiding of attributes, and the attributes were divided into two parts:attribute name and attribute value.In addition, combined with the characteristics of blockchain openness, transparency and tamper-proof, the design of access policy can update the algorithm.Based on the access policy update algorithm, the policy block was added.The new access policy was uploaded to the blockchain to form a policy update traceability chain, which can realize distributed and reliable access control management under the condition of hidden policy.It can also support data privacy protection at the same time, and traceability of user behavior.The theoretical proof and experimental analysis have proved that this scheme protect attribute privacy effectively, while reduces computational overhead.…”

Fine-grained privacy operation control method for layout documents by Peijie YIN, Fenghua LI, Ben NIU, Haiyang LUO, Bin KUANG, Lingcui ZHANG

“…In view of the problem of privacy information disclosure caused by uncontrolled forwarding in the context of frequent exchange of privacy information, a fine-grained privacy operation control method for layout documents was proposed, which could achieve differentiated fine-grained privacy operation control according to the requirements of the sharer during the sharing process of privacy information.For the received multimodal layout document, the existing privacy operation control strategy was extracted, which combined the current sharer’s use attribute and the receiver’s privacy protection ability and other factors.The privacy operation control strategy was generated iteratively, and an abstract control strategy generation algorithm framework was given.Based on the iterative privacy operation control strategy and combined with specific operation scenarios, the differentiated data-masking control, exchange boundary control and local use control were carried out for different modes of information components, and the abstract privacy operation control algorithm framework was given.A prototype system for privacy operation control of OFD (open fixed-layout document) was developed to verify the above algorithms.The generation and delivery of iterative privacy operation control strategy based on friendship, as well as the differential data-masking control, exchange boundary control and local use control of OFD were implemented in the instant messaging system.…”
