A client terminal data collection method and apparatus, for compressing data parsing volume, greatly increasing the efficiency of character string checking, said method comprising: receiving a data upload request sent by a client terminal (101); calculating a first feature value for first data (102); looking up whether feature information produced on the basis of second data corresponding to identification information (103) is stored; when finding said feature information, determining whether the length of a first character string is the same as the length of the character string (104); when the length of the first character string is the same as the length of a second character string, determining whether the first feature value is the same as the second feature value (105); if so, then refusing to write the first data (106); if not, then writing the first data to cover the second data (107). |
