Abstract
A method and associated system. A server computer selects a re-ordering scheme from one or more re-ordering schemes, for re-ordering chunks of an original tile. The server computer divides the file into the chunks. After the file is divided into the chunks, the server computer re-orders the chunks according to the selected re-ordering scheme to form an obfuscated file that includes the re-ordered chunks. The server computer sends, to a client computer, the obfuscated file along with a scheme access reference that enables the client computer to access the selected re-ordering scheme.
Claims20
A method, said method comprising:
- selecting, by a server computer, a re-ordering scheme from one or more re-ordering schemes for re-ordering chunks of an original file;
- dividing, by the server computer, the file into the chunks;
- after said dividing the file into the chunks, re-ordering, by the server computer, the chunks according to the selected re-ordering scheme to form an obfuscated file comprising the re-ordered chunks;
- and
- sending, by the server computer to a client computer, the obfuscated file along with a scheme access reference that enables the client computer to access the selected re-ordering scheme.
A computer program product, comprising one or more computer readable hardware storage devices having computer readable program code stored therein, said program code containing instructions executable by one or more processors of a server computer to implement a method, said method comprising:
- selecting, by the server computer, a re-ordering scheme from one or more re-ordering schemes, for re-ordering chunks of an original file;
- dividing, by the server computer, the file into the chunks;
- after said dividing the file into the chunks, re-ordering, by the server computer, the chunks according to the selected re-ordering scheme to form an obfuscated file comprising the re-ordered chunks;
- and
- sending, by the server computer to a client computer, the obfuscated file along with a scheme access reference that enables the client computer to access the selected re-ordering scheme.
A system comprising a server computer that comprises one or more processors, one or more memories, and one or more computer readable hardware storage devices, said one or more hardware storage device containing program code executable by the one or more processors via the one or more memories to implement a method, said method comprising:
- selecting, by the server computer, a re-ordering scheme from one or more re-ordering schemes, for re-ordering chunks of an original file;
- dividing, by the server computer, the file into the chunks;
- after said dividing the file into the chunks, re-ordering, by the server computer, the chunks according to the selected re-ordering scheme to form an obfuscated file comprising the re-ordered chunks;
- and
- sending, by the server computer to a client computer, the obfuscated file along with a scheme access reference that enables the client computer to access the selected re-ordering scheme.
