Definitions
"Secrecy" is a state in which information is withheld, whether private or confidential.
"Privacy" refers to the condition of limited access to a person and is a much broader concept than limited access to information about a person. Infringement of privacy occurs when unauthorised access is gained to an individual's privacy.
"Confidentiality" is concerned with keeping secret information given to a person by another person. Infringement of confidentiality occurs when the receiver or holder of that information fails to protect or deliberately discloses that information to someone else without the giver's consent.
"Security of information" is a broader concept than confidentiality, embracing the protection of privacy and confidentiality and also integrity and accuracy. In general it refers to the processes, both technical and organisational, necessary to protect information collection, storage and transmission.
Requirements in e-commerce:
An important aspect of e-business is the area of e-commerce. One of the most severe restraining factors for the proliferation of e-commerce, is the lack of trust between customers and sellers, consumer privacy concerns and the lack of security measures required to assure both businesses and customers that their business relationship and transactions will be carried out in privacy, correctly, and timely. This paper considers trust privacy and security issues in e-commerce applications and discusses methods and technologies that can be used to fulfil the pertinent requirements.
