Summary:The embodiment of the invention specifically discloses a service cooperative processing method and device based on privacy protection, a medium and equipment. The method comprises the following steps: acquiring a coordination public sequence; the coordination public sequence refers to a sequence disclosed after a coordination privacy sequence is processed by using a position disruption algorithm; the coordination privacy sequence is used for representing an element position adjustment mode of the basic privacy sequence in a ciphertext form; using a position scrambling algorithm to perform scrambling processing on the position of each element in an initial target privacy sequence fragment held by a specified service party in the initial target privacy sequence to obtain an intermediate target privacy sequence fragment; performing position adjustment on the intermediate target privacy sequence fragment by using the coordination public sequence to obtain a target privacy sequence fragment after position updating
