Smart phones have advanced at a very fast pace in recent years. These advancement leads to the concern of exploitation of users’ personal information due to non-restricted usage of data by any third party applications. Mobile crowdsourcing has evolved as an appropriate method for collecting the data or finding solution of a broadcasted task where the mobile phone users can perform the task anytime and anywhere as they wish. However, sensitive information like location, contact details etc. are provided by mobile users for validation which may results in the privacy breach as the data could be misused. There have been many researches to find some tools for ensuring privacy of the mobile phone users. However, the appropriateness of these tools may not be identified by the users which require additional protection of the data to maintain the confidentiality. The motive of this research is to provide secure environment for the users or workers of crowd sourcing by protecting their personal and sensitive information. Therefore, SALT cryptography is used in proposed solution for ensuring the privacy. SALT is used as a noise with the user’s personal information so that only the valid users will be able to access the information. The obtained results are in well support of the proposed solution.
