John's response effectively details his experience with implementing security measures in a mobile banking application, which is highly relevant to the question. He mentions the use of hashing algorithms, encryption of API calls, SSL pinning, and the prevention of clear text traffic, all of which are important security practices. However, his response could be more concise and structured for better clarity. Additionally, he could mention any specific outcomes or feedback received as a result of these security implementations, as well as any challenges faced and how they were overcome, to provide a more comprehensive answer similar to the benchmark response.
