Energies Free Full-Text Roaming Service for Electric Vehicle Charging Using Blockchain-Based Digital Identity

Identity management is the framework of processes, policies, and technologies to ensure that only authorized people have access to technology resources, information, or services. Identity and access management systems are continuously evolving to improve security and the user experience. The importance of better security in identity management is not limited only to logging into our social media accounts. Many of the critical infrastructures such as grids and power plants are still subject to password protection.

• The first is authentication, where the public key verifies that a holder of the paired private key sent the message.
• Experts have been contemplating the summation of various identifying information like demographic and employment related data and even information about the individual revealed by other people.
• Together, these various elements are needed for the bank to verify the account-holder’s identity.
• UEM software is vital for helping IT manage every type of endpoint an organization uses.
• Without the consent from the majority of computers, no one can add any transaction blocks to the ledger.
• And, the bright side that ties everything together is the growth of the blockchain market.

Figure 4 presents the information exchanged to initialize the charging process between these participants in the process. The EVO initiates the charging process by establishing a connection with the CS. The EVO, employing her/his mobile app, reads the connect invitation QR code displayed on the CS or accesses that information from an internet listing and establishes a peer-to-peer connection with the CS. After establishing the CS connection, the EVO sends a message to the CS requiring a charge session to be initiated (and providing the CS with the charging parameters, i.e., time, max current, etc.). In response to the charging request, the CS requires the EVO to present proof that she/he owns a valid VC. The user selects the claim from the list of valid VCs that can be used to answer the presentation requests and presents the selected VC to the CS.

How does blockchain verify identity?

The decentralized nature of blockchain is particularly useful in the case of digital identities as it reduces the risks of compromises in data. Technology is gradually integrating with almost every facet of our lives, thereby presenting the need to focus more on digital identity and data privacy in the cyber landscape. Digital identity is quite a crucial term in the existing time where consumers are adopting the internet for carrying out online transactions throughout multiple devices.

If you’re using your phone as a digital identity wallet, you’ll want to be just as careful as you would be with your physical wallet. What can you do if your phone has been lost or stolen, and your credentials are stored in the Sovrin Network? All you would have to do is create a new credential for your digital identity. The blockchain identity management ecosystem is growing fast and the most important usecase is the drive to bridge the gap between the real world and blockchain tech by making wallet creation seamless.

Maintaining different authentication profiles is quite a challenging task. The question of which approach will ultimately prove more successful remains unsettled. Some may prefer the solution proposed by Blockstack, as the hugely ambitious goal of creating an entirely new internet has profound implications well beyond the field of security or identity management.

Immutability — the inability to delete records on a ledger — is beneficial to security, but it can affect the privacy of PII. Determining what information stays on-chain vs. off-chain is important for other criteria on this list. On-chain immutability must balance requirements and safeguards across parties. Shifting from a centralized to distributed paradigm requires interconnectivity and coordination of data, APIs, systems and governance mechanisms.

With different consumption rates , several electric devices were used to evaluate the precision and accuracy of the current measures gathered by the energy measurement device. The stability of the device after an extended period of continuous usage was evaluated. The accuracy and precision levels measured are in line with the published information for the current transformer. After the device calibration, the current values measured reported a 5% error on average regarding the device stability; during extended periods of continuous usage, no significant impacts on the device behaviour were observed. After receiving the charging request message and a VC that confirms that EVO is authorized to use the CS and charge the EV, as previously presented in Figure 4, the CS starts the charging process.

Blockchain designs can ensure personal information, verifiability and the proper controls follow users when they transition from one organization to another. These designs can be adapted to facilitate this process in a timely manner. Consensus algorithms used for verification and distributed access affect the speed and computing power required to deliver service-level agreements in a scalable and sustainable way.

However, the massive centralized systems come with single points of failure, and the personally identifiable information of user accounts stored in the systems makes them attractive to hackers. Recent reports have suggested that personally identifiable information is the most preferred target in breaches, with around blockchain identity management 97% of all breaches in 2018 involving PII data breaches. On the other hand, around 60% of the 2.7 billion people in the world without access to banking services own smartphones. Therefore, blockchain-based mobile identity solutions could serve as promising answers for the needs of vulnerable citizens worldwide.

The Problem With The Current Process

Centralized identity management is when a single authority collects and stores user data. Federated identity management allows authorized users to access multiple applications and domains with a single set of credentials such as when people use their Google or Facebook account to sign into apps and websites. A digital identity is the total information about an individual or organization that exists online. Data that forms a digital identity includes usernames, buying history, ID number, and search history. Almost all of our digital identities are connected through devices, services, and apps that have dominantly used centralized and federated identity systems.

Rather than having PII replicated and stored across hundreds of organizations, information and sharing controls could remain with the end user. As more and more of our lives are spent online and the physical world grows ever more digital, the very notion of identity is changing dramatically. Authentication of who we are and how we are represented online has become paramount to both individuals and organizations. People want power over their identities and control over how and with whom their information is shared.

In this process, identity management regarding EV drivers and Charging Stations plays a critical role in allowing flexibility and interoperability among different charging systems. We implement blockchain-based digital identity management using Hyperledger Indy/Aries. This approach avoids charging specific cards used as an authentication process among charging systems. In this scenario, interoperability among different countries can be reached, allowing an EV charging roaming process. Additionally, CSs can be joined through the authentication process, allowing private entities participating in this charging approach to increase the number of charging spots.

Figure 17 presents the hardware selected to manage and monitor the CS process. The CS controller is mainly composed of a Raspberry PI Zero W , providing the computing power required to support the BC-based identity management software and the controller-specific software. The current delivery to the EV is measured with a non-intrusive device , which behaves as a current transformer, exposing the device terminals to a fraction of the current being passing through the circuit under measurement.

Future Proofing Identity-Management with Blockchain

As a result, these automated authorization systems are becoming increasingly common. In today’s digital world, a person’s online identity is becoming just as valuable as their real-world identity. Our online activity, combined with the information we leave behind, creates a personal digital identity that businesses, organizations, and other individuals pick up. Accenture, along with Microsoft and Avanade, created a blockchain-based identity management tool that was presented at ID2020 Summit. Built on the guiding principles of open standards and interoperability, IBM’s ready-to-use blockchain-based offerings work with credentialling solutions around the world.

A digital identity may be a pseudonymous profile linked to the device’s IP address, for example, a randomly-generated unique ID. Data points that can help form a digital identity include usernames and passwords, drivers license number, online purchasing history, date of birth, online search activities, medical history, etc. Biometrics, Behavioral, Biographic are the modals that make up a person’s identity. For example, games based on blockchain transactions, like Enjin, use daemon wallets to send and receive transaction requests. However, without a daemon wallet, users must manually sign every transaction using a crypto wallet, making for an infinitely more cumbersome experience.

Now, as soon as they get those assets, the fun begins for business owners. Coinbase recently gave the wide public image of how this can be done by partnering with Remitly and allowing consumers to cash out digital currencies with minimal fee. Blockchain technology can enable end-to-end traceability of goods in the delivery process. This can help identify any problems or issues that arise in the supply chain — defective products, ineffective routes, or delivery delays.

The ADC used is designed to convert a tension value to a digital value; to convert the current measured into tension, a small electronic circuit is added between the current sensor and the ADC. While the majority of people might only know the blockchain in regard to cryptocurrency, there are some organizations out there that understand the benefits a blockchain can bring to networking and secure online exchanges. One association like this is the Sovrin Foundation, which founded the Sovrin Network.

The VC data that is accessible to all supply chain stakeholders act as a shared source of truth that can’t be tampered with. The faster verification process is enabled by the use of cryptography and the instant verification of the issuer such as a driver’s licensing organization or bank. A verifier can check the blockchain to see the Issuer’s public cryptographic key and confirm if the VC was really issued by them. Anyone in the world can be part of the network with a digital identity as long as they have at least a mobile phone. The system automatically updates verified data to all of the stakeholders in the network and acts as a trusted single source of truth that is maintained by the blockchain.

Without a daemon wallet, it would be necessary to sign every in-game blockchain transaction via a crypto wallet. The ID2020 initiative, meanwhile, is a global partnership committed to ushering in the next era in ID management. Its alliance includes BLOK Solutions and Accenture, two startups specializing in blockchain digital identity services.
