The study of data-oriented and ownership-based security architecture in open internet environment

DOSA (Data-Oriented Security Architecture, or Data Ownership-based Security Architecture) is an architecture for data protection and application in an open Internet environment. DOSA combines data with ownership by using digital certification authentication (CA) and public key infrastructure (PKI). The DOSA is simply described as one body with two wings. The one body is that the data must be combined with ownership. The one wing is that the data should be innately registered. Another wing is that the data should be innately encrypted with the data owner's public key. To share data and make data applicable, DOSA also establishes the authorization of data ownership for data sharing, the recording of data operation for data history tracing, the data behaviour analysis for the discovery of illegal use of data, and the data usage statistics for the assessment of data value, etc. Therefore, data can be securely shared and used in an open environment with ownership authorization. At the same time, data ownership is clarified; the interests of the data owner can be guaranteed.
