Client Device Signature Caching for Malware Detection Latency

The patent extracts the signature database from the client device and relocates it to a remote server. The client device maintains only a minimal local database for frequently accessed signatures, while the majority of signatures are stored remotely and accessed over the network. This extraction resolves the contradiction by removing the bulk of the database from the client, reducing local processing resource consumption and scanning time while maintaining detection accuracy through remote access to the comprehensive signature database.

The patent introduces a remote server as an intermediary between the client device and the comprehensive signature database. The server acts as a mediator that stores the full signature database and provides selective access to the client device. This intermediary resolves the contradiction by enabling the client to access a large database remotely without maintaining it locally, thus reducing local processing requirements while preserving detection capabilities.

The patent applies preliminary action by proactively caching frequently requested signature information at the client device before it is needed for scanning. The system predicts which signatures will be required and pre-loads them into the local cache, so when scanning occurs, the signatures are already available locally. This resolves the contradiction by eliminating communication latency for frequently accessed signatures while maintaining the benefits of remote database access for less frequent signatures.

The patent creates a copy of frequently accessed signature information at the client device through caching mechanisms. Instead of always accessing the remote server, the client maintains local copies of commonly needed signatures. This copying resolves the contradiction by providing immediate local access for frequent scanning needs while preserving the remote database as the source of truth for all signatures.

The patent performs preliminary action by pre-fetching and caching signature information that is likely to be needed for upcoming scanning operations. The system analyzes file metadata and scanning patterns to predict future signature requests and proactively loads those signatures into the local cache. This resolves the contradiction by reducing the frequency of network requests while maintaining detection accuracy through having signatures available locally when needed.

The patent implements self-service by enabling the client device to autonomously manage its own signature caching based on local scanning patterns and predictions. The system automatically determines which signatures to cache and when to refresh them without constant server intervention. This self-service approach resolves the contradiction by optimizing network bandwidth usage while maintaining detection accuracy through intelligent local signature management.
