Techniques are provided for detecting modifications to software instructions. At a computing apparatus configured to execute a software program comprising a plurality of instructions, at least a first check point having a first check value and a second check point having a second check value are assigned within the instructions. At least first and second portions of the instructions are identified. The first portion of the instructions comprises one or more check points other than the first check point. The second portion of the instructions comprises one or more check points other than the second check point. A first hashing operation is performed over the first portion resulting in a first equation and a second hashing operation is performed over the second portion resulting in a second equation. The first check value and the second check value are computed based on the first equation and the second equation. |
