Mistaken identity, identity theft and problems of remote authentication in e-commerce

The problem of mistaken identity in e-commerce transactions brings together seemingly unrelated issues: privacy, network security, digital signatures – and classic contract law. Combining an academic exercise with the practical implications of the insecurity of the Internet, this paper draws some unexpected conclusions regarding cases of mistaken identity and exposes flaws in popular legal arguments on the subject. Problems of mistaken identity must be analysed afresh with a number of factors in mind: the more widespread use of fictitious identities in on-line transactions, the higher incidence of identity theft and the greater difficulty of authenticating the other transacting party. The trend to preserve the privacy of Internet users indirectly clashes with efforts to ensure transactional security in e-commerce. An indispensable prerequisite of the latter is the ability to identify the other party to the contract. The problem of mistaken identity is not new – but it assumes a different scale in e-commerce transactions.
