Efficiency of extraction and conversion of pseudoephedrine to methamphetamine from tamper-resistant and non-tamper-resistant formulations

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...

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 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...

Tamper-resistant ubiquitous data management

The rapid growth of ubiquitous computing impels mobile users to store personal data on the Web in order to increase data availability and facilitate data sharing among partners. However, Database Service Providers (DSP) arouse user’s suspicion because DSP’s privacy policies have been frequently dishonored [AKS02]. In addition, no one can fully trust traditional server-based security mechanisms ...
