Abstract: Methods and systems are disclosed for managing access to encrypted data and encryption keys. The system stores, by a key management server, a first encryption key associated with a first service and a second encryption key associated with a second service. The system prevents, by the key management server, the second service from accessing the second encryption key while the first service is performing a first function using the first encryption key and determines that a first threshold period of time associated with the first function has elapsed. The system, in response to determining that the first threshold period of time associated with the first function has elapsed, prevents, by the key management server, the first service from accessing the first encryption key while the second service is performing a second function using the second encryption key.

Abstract: Methods and systems are disclosed for performing private identification matching. The methods and systems store, by a first entity, a first set of private identifiers associated with a first set of data. The methods and systems group, by the first entity, different subsets of the first set of private identifiers into respective buckets of a first plurality of buckets according to a grouping criterion. The methods and systems apply a function to a subset of a second set of data, stored by a second entity, corresponding to private identifiers associated with one or more buckets of a second plurality of buckets, grouped by the second entity, that match private identifiers associated with one or more buckets of the first plurality of buckets. The methods and systems provide, to the first entity, a result of applying the function to the subset of the second set of data.
