Claim 22:
23. A system, comprising:
at least one apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause an apparatus at least to perform or control:
obtaining or causing obtaining an image of at least a part of a surface of a first sealed unit;
deriving or causing deriving a representation of the at least a part of the surface from the image, the representation comprising a set of values respectively representing a corresponding set of height levels of corresponding sections of the at least a part of the surface;
generating or causing generating a first string of characters based on the representation of the at least a part of the surface, the first string of characters comprising at least a first portion representative of the set of height levels of the corresponding sections of the at least a part of the surface and a second portion generated based on a function of the representation and/or of the first portion of the string of characters; and
associating or causing associating first information representing the first string of characters with identification information of the first sealed unit; and

at least one apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause an apparatus at least to perform or control:
obtaining or causing obtaining first information representing a first string of characters with a first portion representative of a set of height levels of corresponding sections of at least a part of a surface of a first sealed unit;
determining or causing determining, based on the obtained first information, whether or not the first string of characters is present in a database; and
if the first string of characters is present in the database:
outputting or causing outputting confirmation information;

if the first string of characters is not present in the database:
determining or causing determining, based on a metric function, whether or not at least one second string of characters is present in the database, a distance of which to the first string of characters is below a first predefined threshold; and
outputting or causing outputting the confirmation information if at least one second string of characters is present in the database, the distance of which to the first string of characters is below the first predefined threshold.
