    Develop a function that enhances fraud detection by activating all high-priority security checks in a transaction pattern, where each even bit position represents a critical verification point. The function should set all even-positioned bits to 1 in the binary pattern while preserving the original state of odd-positioned indicators, ultimately strengthening the transaction's security validation process.
