Digital watermarking for authenticity and security in lifecycle management of digital content

A non-transitory computer-readable storage medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations for digital watermarking of digital content for information lifecycle management (ILM), the operations comprising:

• receiving first digital content comprising an image;
• initializing parameters for the first digital content;
• converting a first set of values of the first digital content to a second set of values, the first set of values being representative of the image in a first color space and the second set of values being representative of the image in a second color space;
• dividing a sub-set of values of the second set of values into a set of blocks;
• applying a transform to each block in the set of blocks to provide, for each block, a frequency domain representation of at least a portion of the image;
• for each block in the set of blocks, embedding a sub-set of watermark bits from a set of watermark bits into the block based on the parameters, the set of watermark bits being representative of a digital watermark representing at least one value for execution of an ILM activity;
• executing an inverse transformation of the set of blocks to provide a modified second set of values representative of the image with the digital watermark in the second color space;
• converting the modified second set of values to a modified first set of values representative of the image with the digital watermark in the first color space;
• and
• providing second digital content comprising the image with the digital watermark.
