Is it possible to apply the same hash function to recover the original data from a hash value?

No, a hash function is not designed to recover the original data from the hash value. It is one-way: a hash is computed from the input data, but the original data cannot be obtained from the hash.
Hash functions are used for integrity verification or storing passwords (as hashes), but not for recovery. If a reversible operation is needed, encryption is used instead of hashing.
