Abstract: A server access log includes data records each describing a previous query regarding a suspect computer file of a client computer. Each record includes the CRC code for the suspect computer file, the result of the malware analysis performed on the backend server and other attributes and values. The log is analyzed to retrieve relevant attributes and values from each record. Key attributes and values are generated such as region and continuous query. All CRC codes are grouped according to attribute values. Each group is analyzed to determine the network traffic associated with downloading the entire group to all user computers and the network traffic associated with not downloading the group but responding to future malware queries regarding CRC codes in the group. CRC codes are removed from each group if necessary. CRC code-result pairs for each group are downloaded to all user computers as a pre-fetch cache.

Abstract: An incentive mechanism for encouraging the adoption and use of a communally useful entity. Use of the communally useful entity is tracked. An incentive payment to be paid by an incentive provider to a recipient is calculated, the recipient being the designee of a user of the communally useful entity, and the incentive payment proportionate to a measure of the user's use of the communally useful entity. The incentive provider is directed to distribute the incentive payment to the recipient, and an amount of rights to participation in the communally useful entity is distributed to the incentive provider's designee, where the amount of rights to participation distributed is proportionate to the value of the incentive payment made by the incentive provider. Thus, the user is given an incentive to use the transaction platform, and the incentive provider is given an incentive to encourage others use of the transaction platform. A software program and computer-based system are also disclosed.
