Data Security Issues in Data Publishing
HweeHwa Pang
Institute for Infocomm Research, Singapore
In the data publishing model, the data owner deposits his data(base) with
a third-party server that stores the data and executes user queries. As
the 3rd-party server may be vulnerable or even untrusted, the model
introduces several challenging data security issues over conventional
client-server architectures. These include building in safeguards against
theft and sabotage of the data, provisions for users to verify the
correctness and completeness of query results, and fine-grained access
control. This talk will give an overview of the data security issues, and
also share some of our results.
