Since its inception, blockchain has promised many benefits as against the centralized traditional methods of data storage. Apart from its transparency and ability to withstand security challenges through immutability, it provides faster processing data speed and a wide range of real-life applications. Because of this, many industries have begun to leverage blockchain technology while others are still in the process of venturing into it. These benefits in recent times have been tapped into different sectors of the economy such as banking and finance, transportation, healthcare, education, and even non-fungible assets like the NFTs. Taken from this background, this article aims to establish how blockchain can be applied in the Global Positioning System (GPS) for surveillance.

Blockchain and GPS Surveillance: Prospects and Challenges

Global Positioning Systems are one of the recent sectors considering the application of blockchain to its ways, and the advantages of this application are numerous, especially for GPS users. Let us therefore take a cursory look at how blockchain technology can be leveraged in surveillance and GPS mapping.

Below are some of the benefits of integrating blockchain into GPS surveillance and mapping:

•Timestamping: One of the outstanding things about blockchain technology is that information concerning the time a certain action was carried out is usually indicated. In other words, the blockchain has a timestamp for every single action carried out, hence the difficulty in manipulating data on the blockchain. This timestamping can be adopted into GPS surveillance to provide and validate when certain data are entered into the GPS server. This way, one can track when a certain GPS location was entered. Most traditional GPS systems do not have this function and it's always difficult to mark the exact time when a certain person was at a certain place even when the exact position is established. Blockchain can solve this problem and ensure that timestamping is properly integrated into GPS surveillance.

Again, blockchain records the history of data changes and transactions, which can be important for GPS applications. Users can verify the source of location data and assess its trustworthiness. This can be particularly useful for fleet management, logistics, and supply chain tracking.

•Interoperability: Blockchain can promote interoperability among different systems or devices used in Global Positioning Systems and the different data sources used in establishing exact positions used by end-to-end users. What this means is that different platforms connected to the GPS can communicate and share data securely from one device or system to another. This in turn will promote the efficient positioning and tracking of locations which are all the main aims of GPS surveillance.

•Smart Contracts: Smart contracts are simply a set of rules on the blockchain that automatically or smartly execute a set action once the conditions are met. This smartness of the blockchain can be leveraged in GPS surveillance and mapping. For instance, a certain condition can be set that once an individual or a car enters a certain location, such an individual's location should be tracked for security reasons. This will be done automatically on the GPS since such conditions are automated to work smartly. Hence, this can ensure effective GPS surveillance and tracking.

•Privacy and Consent Management: Privacy and consent management are crucial aspects of leveraging blockchain technology in GPS surveillance and mapping applications. For instance, data ownership and control would be ensured as blockchain allows users to have greater ownership and control over their location data. Individuals can store their GPS data on a blockchain and grant or revoke access to it using cryptographic keys. This puts the power of data ownership in the hands of the data subjects. Again, consent for data usage can be recorded as transactions on the blockchain. Users can specify the conditions under which their GPS data can be accessed or shared. This information can be audited, and users can be notified whenever their data is accessed, ensuring transparency.

•Decentralization of Data: Developers can create DApps that utilize blockchain-based GPS data. These DApps can offer a wide range of location-based services, from navigation and asset tracking to augmented reality applications. By implication, this means Decentralized Applications (DApps) that utilize blockchain-based GPS data have the potential to offer a wide range of innovative location-based services that can aid GPS surveillance and mapping. Thus, DApps can leverage the trust and security provided by blockchain technology to create new opportunities for geo-mapping and location tracking.

•Accurate Navigation Services: Decentralized Applications (DApps) can provide Global Positioning Systems (GPS) navigation services that are more accurate and secure due to the immutability of location data stored on the blockchain. Users can trust the navigation routes and receive real-time traffic and map updates.

Blockchain and GPS Surveillance: the Challenges Involved

Integrating blockchain technology into GPS surveillance and mapping systems presents both opportunities and challenges. While blockchain can potentially enhance the security, transparency, and trustworthiness of location-based services, there are several complex challenges to overcome. Some of the key challenges involved in integrating blockchain into GPS surveillance and mapping are:

•Scalability:

Blockchain networks often suffer from scalability issues, which could affect the real-time performance of GPS systems. Processing a large number of location data points on a blockchain can lead to slow transaction confirmations and increased cost. Solutions like shading and layer 2 solutions are being explored to address this issue.

Again, the data volume of GPS is heavy and high and the location data generated by GPS devices is vast and continuous. Storing all this data on a blockchain can lead to significant storage requirements and could make the blockchain slow. Implementing efficient data compression and pruning techniques is crucial here to overcome this particular challenge.

•Consensus Mechanism:

The choice of a consensus mechanism can significantly impact the performance and security of a blockchain used in GPS surveillance. Proof-of-Work (PoW) and Proof-of-Stake (PoS) may not be suitable for real-time applications due to latency issues. Alternative consensus mechanisms, such as Delegated Proof-of-Stake (DPoS) or Directed Acyclic Graph (DAG), maybe more suitable. Even with this, POS seems to be the most effective since it involves less energy and it is environmentally friendly.

•Cost and Energy Efficiency:

Running a blockchain network can be expensive in terms of computational power and energy consumption. It therefore becomes crucial to find efficient consensus mechanisms and explore eco-friendly blockchain solutions to reduce the environmental impact. Hence, integrating blockchain and GPS demands a huge capital for its success.

•User Adoption and Trust

Convincing users to trust a blockchain-based GPS is a significant challenge. Ensuring that users understand the benefits of blockchain, such as improved security and transparency, while addressing their concerns about privacy and data security is essential. They are always afraid of the safety of their data. At the same time, some of them are so used to centralized GPS surveillance and mapping that they are not even ready to embrace the integration of blockchain technology into GPS surveillance.

Other challenges include:

•Privacy concerns with end user's data

•The complex process of verifying the authenticity of GPS data

•Interoperability challenges

•Data authentication challenges

•Use and storage of GSP data on Blochain may raise regulatory and legal concerns.

Conclusion:

As we now live in a world where we need GPS surveillance and mapping in our everyday activity and location data plays an increasingly pivotal role in our lives, the incorporation of blockchain technology promises a new era of privacy and consent management. With the power of blockchain, individuals can claim their rightful ownership over their location data and have the autonomy to decide who accesses it and under what circumstances. This newfound control would not only safeguards personal privacy but also empowers users to play a pivotal role in the data-sharing ecosystem. Integrating blockchain into GPS surveillance and mapping systems has the potential to enhance trust and security, but it also presents various complex challenges. Overcoming these challenges requires a combination of technical innovations, cryptographic techniques, efficient consensus mechanisms, and regulatory compliance. Addressing these issues can also pave the way for more secure and transparent location-based services in the future.
