Method for the generation of personalized profile packages in integrated circuit cards, corresponding system and computer program product

A method for generating personalized profile package data, the method comprising:

• providing, by a profile making entity, a table comprising a plurality of data records (R1 . . . Rn) corresponding to a plurality of profile data, each data record (R1 . . . Rn) comprising a plurality of personalization fields (T1 . . . Tm) to store different types of personalization values (V1 . . . Vm);
• providing, by the profile making entity, a master profile comprising fields to be personalized (F1 . . . Fk . . . Fp) corresponding to one or more of data records (R1 . . . Rn) to store the different types of personalization values (V1 . . . Vm);
• combining, by the profile making entity, the one or more data records (R1 . . . Rn) in the table with the master profile by inserting the personalization values (V1 . . . Vm) in the fields to be personalized (F1 . . . Fk . . . Fp), wherein combining comprises using an offset table indicating for each personalization field (Fk) of a data record (R1 . . . Rn) an offset address (AV) of the master profile at which the personalization value (V1 . . . Vm) is to be inserted;
• coding, by the profile making entity, the one or more data records (R1 . . . Rn) to be combined with the master profile with a type length value coding, wherein coding comprises associating a tag (Gj) to a personalization field (Tj), a length (Lj) of a value (Vj) inside the personalization field (Tj), and the value (Vj) itself, thereby obtaining encoded data records (CRi);
• applying, by the profile making entity, the coding to the offset table, wherein applying comprises associating a tag (AG) to the personalization field (Tj), a value length (ALj) of a value (AVj) to an offset address content (AVj), thereby obtaining encoded data offset (COi);
• and
• combining, by the profile making entity, for each record (Ri) the encoded data record (CRi) and the data offset (OCi) in an encoded personalization record (URi, EURi).

A computer-program product to be stored in a non-transitory computer readable storage medium for execution by a processor, the program product including instructions for:

• providing a table comprising a plurality of data records (R1 . . . Rn) corresponding to a plurality of profile data, each data record (R1 . . . Rn) comprising a plurality of personalization fields (T1 . . . Tm) to store different types of personalization values (V1 . . . Vm);
• providing a master profile comprising fields to be personalized (F1 . . . Fk . . . Fp) corresponding to one or more of data records (R1 . . . Rn) to store the different types of personalization values (V1 . . . Vm);
• combining the one or more data records (R1 . . . Rn) in the table with the master profile by inserting the personalization values (V1 . . . Vm) in the fields to be personalized (F1 . . . Fk . . . Fp), wherein combining comprises using an offset table indicating for each personalization field (Fk) of a data record (R1 . . . Rn) an offset address (AV) of the master profile at which the personalization value (V1 . . . Vm) is to be inserted;
• coding the one or more data records (R1 . . . Rn) to be combined with the master profile with a type length value coding, wherein coding comprises associating a tag (Gj) to a personalization field (Tj), a length (Lj) of a value (Vj) inside the personalization field (Tj), and the value (Vj) itself, thereby obtaining encoded data records (CRj);
• applying the coding to the offset table, wherein applying comprises associating a tag (AG) to the personalization field (Tj), a value length (ALj) of a value (AVj) to an offset address content (AVj), thereby obtaining encoded data offset (COi);
• and
• combining for each record (Ri) the encoded data record (CRi) and the data offset (OCi) in an encoded personalization record (URi, EURi).
