Summarization System Based on Latent Semantic Analysis and Anaphora Resolution

The main objective of the project is the developement of a new text summarization method that would take advantage of latent semantic analysis strengths. The proposed method would combine both lexical and anaphoric information.

Securing Access Authentication to Oracle Portal with Digital Signatures

The goal of the diploma work is to increase security of the access authentication into the Oracle Portal with digital signatures. User will need, except a username and a password, his digital certificate for accessing the Oracle Portal. This work solves also the authentication to PL/SQL applications, which is demonstrated on a small demo-application. Topics discussed in this work are: encrypting, message digests, digital signatures, certificate authorities, cerificates and their publishing, user authentication, SSL (Secure Socket Layer), Oracle 9i Aplication Server, publishing certificates with OpenSSL, configuring Oracle HTTP Server, securing user authentication in PL/SQL applications and Oracle Portal.
An exteding theme of this diploma work is an email signing and a signature verifying with language Java.

Duration: 2002 - 2003
