US11943206B2	System and method for authorized digital content distribution A digital content distribution system uses a Digital Rights Management Controller that performs a set of arbitrary tests against the transfer request from one user to another such as user A to user B. Assuming these tests are successful, the DRM sends an encryption key to transferring user A. This encryption key E is taken from a table of encryption key/hash pairs which have been provided to the DRM Controller by an external authority such as the content rights holder. User A encrypts the content using they key provided by the DRM controller and then optionally calculates a hash over the encrypted form of the content E(X) and returns this value to the DRM Controller. On checking the returned hash against the hash from the table the DRM controller knows that user A does indeed have the digital content X in good condition. The DRM Controller then instructs both users A and B that the transfer may proceed. The encrypted form of the content E(X) is transferred from A to B. Once the content transfer has completed B ensures that the received content has been physically written to non-volatile storage (to account for crashes etc. during the next step). B then calculates a hash over the received content and returns this value to the DRM Controller.

An increase rate of the width of the second impurity region in each of sections, obtained by dividing the photosensitive region into n sections in the second direction, becomes gradually higher in the transfer direction. Here, n is an integer of two or more.

The SPAD pixels may be overlapped by square toroidal microlenses to direct light incident on the pixels onto photosensitive regions of the pixels. The square toroidal microlenses may be formed as first and second sets of microlenses aligned with every other SPAD pixel and may allow the square toroidal microlenses to be formed without gaps between adjacent lenses. Additionally or alternatively, a central portion of each square toroidal microlenses may be filled by a fill-in microlens. Together, the square toroidal microlenses and the fill-in microlenses may form convex microlenses over each SPAD pixel. The fill-in microlenses may be formed from material having a higher index of refraction than material that forms the square toroidal microlenses.
