发明名称 Personal computer diary
摘要 A computer diary archives a diary entry by creating, time stamping, authenticating and permanently storing a reference data block along with each diary entry. An archived diary entry can only be modified by placing original text within compartment codes, such as cross-out or tear-out codes, and by placing inserted text within insertion codes so that the original diary entry can be recreated from the modified diary entry. The reference data block, which can be the original diary entry, a canonical version of the original diary entry, or a one way fixed length encryption (hash) of the original diary entry, cannot be modified and is used to authenticate the original diary entry. The diary program also monitors text entry for aliases and relative date phrases, and upon detection, prompts the user for entry or enters a specific identifier for each detected alias in an alias compartment or an absolute date for each relative date phrase in an implied date compartment in the diary entry.
