Abstract: Embodiments of this specification provide methods and apparatuses for data privacy protection. An embodiment of the methods comprises receiving, by a first party from a second party, an encrypted integrated vector, determining an encrypted result vector based on the original matrix and the encrypted integrated vector, determining a data processing result based on the encrypted result vector, and sending the data processing result to the second party for the second party to obtain a multiplication calculation result of the original matrix and the n original vectors based on the data processing result.

Abstract: An electronic device includes a display assembly for displaying images and including a first part and a second part disposed at different sides of a first deformable part of the display assembly, where a first deformability of at least a part of the display assembly includes capability to change a relative angle between the first part and the second part; and a fixing assembly coupled to the display assembly for fixedly connect the display assembly, the fixing assembly including at least a first fixing element. At least a part of at least one of the first fixing element or the display assembly has a second deformability including capability to change a length in a preset direction.
