Methods for executing computer executable instructions

A computer implemented method for executing a first set of computer executable instructions by using at least a third memory portion (123) of a memory (120) of a first computing device (100), the third memory portion (123) being allocated to the first set of computer executable instructions and the first set of computer executable instructions comprising instructions which, when the first set of computer executable instructions is executed by the first computing device (100), cause the first computing device to generate at least a first data item comprising first information,

• wherein the first computing device (100) also executes a second set of computer executable instructions by using at least a first memory portion (121) of the memory (120) of the first computing device (100), the first memory portion (121) being allocated to the second set of computer executable instructions and consisting of a second memory portion (122), the third memory portion (123) and a fourth memory portion (124),
• wherein a third set of computer executable instructions is stored in the fourth memory portion (124) and comprises instructions which, when the third set of computer executable instructions is executed by the first computing device (100), cause the first computing device (100) to store the first information in the second memory portion (122),
• wherein the first set of computer executable instructions has no permission to read from the second memory portion (122) and has no permission to write to the second memory portion (122),
• and wherein the method comprises at least the steps of:
• executing the first set of computer executable instructions by using at least the third memory portion (123) thereby generating the first data item;
• and
• executing the third set of computer executable instructions thereby storing the first information in the second memory portion (122).
