INVESTIGATIONS ON METHODS EVOLVED FOR PROTECTING SENSITIVE DATA

Abstract: This paper reviews strategies evolved for protecting sensitive data for the past 10 years. There has been a steep rise in privacy concerns in today's Internet world. There is a definitive need to provide confidentiality as well as preserve privacy of sensitive data. Confidentiality means that data stored in one place unauthorized is difficulty of impossible to access. Usually confidentiality is achieved by be using access policy or used some cryptographic tools. Privacy means the safety provided to the information, without leaking sensitive information. Considering the case of a medical database to join with a research institution. In that case patient's personal health care information and medical information have to be provided for researchers. Hence, in order to provide every patient record privacy, the database needs to be an anonymized version of the patient record then sent to the researchers. Researchers are provided with anonymized database only. The Evolution of Sensitive Data Preservation techniques are discussed. The sensitive data attack prevention techniques are portrayed. Techniques to protect trajectory sensitive data are also intensively discussed.
