A method for segmentedly encrypting the data in a document print job in a manner which preserves options for post-rendering analysis/processing of selected non-content components, and a print job which comes into existence as a consequence of implementation of this method. The method includes identifying and individuating, within such a job, the content commands as distinguished from the non-content commands, and then, as a consequence of such identifying and individuating, encrypting only data contained within the content commands. In one manner of practicing the invention, all data in the content commands is encrypted. In another manner of such practice, only data which is contained within the content-field portions of the content commands is encrypted. The resulting print job, in one form, is characterized with (a) an encrypted part which includes only data contained within content commands, and (b) a non-encrypted part which includes the balance of data contained within the job. In another form, the resulting job is encrypted only with respect to content-field portions of the content commands. |
