Performing sensitive online transactions using computers found in cybercafes and public libraries is risky. The untrusted nature of these machines creates a target rich environment. A simple keystroke logger, a common payload of many viruses, records and transmits the secret information (e.g., passwords, credit card numbers, PIN numbers) entered into these machines. In addition, sophisticated malware can hijack a user's authenticated session to perform unauthorized transactions masquerading as the user. This paper presents Delegate, a proxy-based architecture that enables a user to access web sites without disclosing personal information to untrusted machines.
