This paper introduces a new security model which reduces the risk of unauthorized data disclosure in an organization’s network. This model will protect confidential information against unauthorized disclosure. The model is effective at preventing intentional and/or unintentional data propagation (e.g. by a disgruntled employee or by means of malware, etc.) The proposed model is a combination of traditional cryptographic-based security methods and Meta-data embedding. The model uses the public key infrastructure cryptosystem and document watermarking technique to attach auxiliary security features (e.g. hash value) into the sensitive documents in order to prevent users from disclosing them without authorization.
