A tracer may obfuscate trace data such that the trace data may be used in an unsecure environment even though raw trace data may contain private, confidential, or other sensitive information. The tracer may obfuscate using irreversible or lossy hash functions, look up tables, or other mechanisms for certain raw trace data, rendering the obfuscated trace data acceptable for transmission, storage, and analysis. In the case of parameters passed to and from a function, trace data may be obfuscated as a group or as individual parameters. The obfuscated trace data may be transmitted to a remote server in some scenarios.
