Abstract:
1. An information processing apparatus that creates a security-protected document to be output based on a determined security level assigned to an object included in an input document without utilizing encryption/decryption or requiring a user to perform an operation, the information processing apparatus comprising: a generation unit configured to extract the object from the input document and store the extracted object in a storage area; an analysis unit configured to analyze the extracted object, update/correct existing metadata information already affiliated with the extracted object, and generate new metadata information identifying an attribute correlated with characteristic information pertaining to the extracted object, wherein the characteristic information derived from an analysis result is added to the existing metadata information associated with the extracted object; a determination unit configured to determine a degradation level for the extracted object in accordance with an analysis result of the extracted object by the analysis unit; and a degradation unit configured to degrade, in a case that the information processing apparatus performs output processing using the extracted object stored in the storage area, the extracted object according to the degradation level determined by the determination unit, and if it is determined that information matching the attribute indicating a characteristic of the object exists, perform degradation processing on the object according to the level of the attribute indicating a characteristic of the matched object; and a storage unit configured to store a table that previously stores an attribute indicating a characteristic of the object which had been extracted from the document and a security level associated with each other, wherein the degradation level is determined by correlating the identified attribute of the extracted object identified in the analysis result, with a determined security level assigned to the identified attribute of the extracted object, wherein the extracted object includes at least one of text, graphic, image and metadata information, and wherein the degradation level is determined according to a combination of an attribute of the object and the security level correlated to the object.
