A Tamper-Resistant and Portable Healthcare Folder

Electronic health record (EHR) projects have been launched in most developed countries to increase the quality of healthcare while decreasing its cost. The benefits provided by centralizing the healthcare information in database systems are unquestionable in terms of information quality, availability, and protection against failure. Yet, patients are reluctant to give to a distant server the co...

A Case for Tamper-Resistant and Tamper-Evident Computer Systems

Recent industrial efforts in architectural and system support for trusted computing still leave systems wide-open even to relatively simple and inexpensive hardware-based attacks. These attacks attempt to snoop or modify data transfer between various chips in a computer system such as between the processor and memory, and between processors in a multiprocessor interconnect network. Software sec...

Tamper Resistant Network Tracing

Raw network traces can be used to compromise the privacy of Internet users. For this reason, many ISPs are reluctant to collect network traces – they often regard possession of such traces as a liability. To mitigate this concern, anonymization techniques have been developed to protect user-identifying information. While most projects anonymize their traces as a post-processing step (i.e., offl...

Tamper-Resistant Biometric IDs

We present FaceCerts, a simple, inexpensive, and cryptographically secure identity certification system. A FaceCert is a printout of person’s portrait photo, an arbitrary textual message, and a 2-D color barcode which encodes an RSA signature of the message hash and the compressed representation of the face encompassed by the photo. The signature is created using the private key of the party is...
