There has been concern over the apparent conflict between privacy and data mining. There is no inherent conflict, as most types of data mining produce summary results that do not reveal information about individuals. The process of data mining may use private data, leading to the potential for privacy breaches. Secure Multiparty Computation shows that results can be produced without revealing t...

Passwords are the foremost mean to achieve data and computer security. Hence, choosing a strong password which may withstand dictionary attacks is crucial in establishing the security of the underlying system. In order to ensure that strong passwords are chosen, system administrators often rely on password auditors to filter weak password digests. Several tools aimed at preventing digest misuse...

The Building Replications Project falls under the umbrella of a larger project, the Private data Sharing Interface (PSI) Tools Project, which seeks to create tools that allow social scientists to more easily access and analyze sensitive data. The PSI Tools Project achieves this goal by applying differential privacy algorithms to datasets, adding noise to the data so that individuals cannot be r...

From e(+)e(-) collision data acquired with the CLEO detector at the Cornell Electron Storage Ring, we observe the non-DD(_) decay Psi(3770))-->gammachi(c1) with a statistical significance of 6.6 standard deviations, using the two-photon cascades to J/Psi and J/Psi-->l(+)l(-). We determine sigma(e(=)e(-)-->Psi(3770))xBeta(Psi(3770)-->gammachi(c1))=(18.0 +/- 3.3 +/- 2.5) pb and branching fraction...

In quantum state filtering one wants to determine whether an unknown quantum state, which is chosen from a known set of states, [|psi(1)>, em leader,|psi(N)>], is either a specific state, say |psi(1)>, or one of the remaining states, [|psi(2)>, em leader,|psi(N)>]. We present the optimal solution to this problem, in terms of generalized measurements, for the case that the filtering is required ...
