Automated access data change detection

A user may conduct a plurality of access requests with a plurality of resource provider computers. A processor server computer may determine whether resource provider computers store access data associated with the user in various ways, including detecting patterns in sets of a plurality of access requests conducted between the user and each of the plurality of resource provider computers. Upon detecting that access data has changed, the processor server computer may automatically send the updated access data to each of the identified resource provider computer. 用户能够对多个资源提供商计算机进行多个访问请求。处理器服务器计算机能够通过各种方式确定资源提供商计算机是否存储与所述用户相关联的访问数据，所述方式包含检测在所述用户和所述多个资源提供商计算机中的每个之间进行的多组多个访问请求中的模式。在检测到访问数据已改变时，所述处理器服务器计算机能够向所述所识别的资源提供商计算机中的每个自动发送所述更新后的访问数据。
