Latest Patents

Chin-Long Shu's latest patents showcase his expertise in Lightweight Directory Access Protocol (LDAP) technologies:

1. **Lightweight Directory Access Protocol (LDAP) Directory Server Cache Mechanism and Method**

This patent describes a method for hierarchical LDAP searching within a directory service, utilizing a relational database management system (DBMS) as a backing store. The method initiates a search query to the relational database, caching search results in two separate caches within the directory service. The first cache stores identifiers indexed by a filter key, while the second cache holds the corresponding entries. This caching system significantly enhances search efficiency by reusing cached data for subsequent queries and includes routines to maintain cache integrity during directory operations.

2. **Reverse String Indexing in a Relational Database for Wildcard Searching**

This innovation presents a method for hierarchical LDAP wildcard searching, involving the generation of a reverse index alongside a forward index of character strings in a relational database. Depending on the placement of wildcards, either or both indices are utilized to form the necessary relational database query, thus improving search capabilities.
