1. A system for classifying a suspicious text message, the system comprising:
a database operable to store known hashed malicious data, wherein the known hashed malicious data comprises known malicious data converted into a hash value using a hashing function;
a blockchain network comprising a plurality of network nodes that form a distributed network configured to maintain a blockchain, each network node of the blockchain network comprising a blockchain processor configured to distribute hashed information data associated with the suspicious text message among the plurality of network nodes;
a classification processor operably coupled to the database and the blockchain network, the classification processor configured to:
receive the suspicious text message from a user device, the suspicious text message comprising information data;
apply the hashing function to the information data of the suspicious text message to generate hashed information data;
store at least a portion of the hashed information data in one or more of the plurality of network nodes in the blockchain network;
compare the hashed information data to the known hashed malicious data in the database; and
classify, based on the comparison, at least a portion of the hashed information data associated with the suspicious text message as containing malicious data.
