When applied to telemedicine, blockchain will further establish an effortless exchange of information and augment consumer confidence in the system. At a fundamental level, blockchain applications enable secure, absolute, and anonymous transactions across networks to arbitrate mutually agreed upon communications between parties.
FREMONT, CA: Despite the handiness of telemedicine, the technology raises mammoth potential security concerns. If the virtual connection between a patient and doctor is not secure, there is a possibility that patients’ location, data, and other sensitive data could be leaked.
The privacy risks connected with telemedicine mostly curtail from the lack of security controls over the gathering, use, and sharing of data.
Third-party Access to Personal Data
Home telehealth sensors and devices may collect and transmit information on activities in the household that a patient wishes to keep private, like their daily routine. Additionally, the practice also includes when the home is unoccupied during particular times of the day.
The highly personal information may be stored or transmitted by a device, letting third-party users access it. Besides, while smartphone applications are useful tools to help manage own health, they are viable to share sensitive data with advertisers and other third parties. The instance comprises sensor data on the location that allows third parties and advertisers to access an individual’s site and store the data in their online servers or libraries.
When applied to telemedicine, blockchain will further establish an effortless exchange of information and augment consumer confidence in the system. At a fundamental level, blockchain applications enable secure, absolute, and anonymous transactions across networks to arbitrate mutually agreed upon communications between parties. In the healthcare industry, distributed ledger technology can help facilitate a more competent way to transfer information effectively and converse across organizations.
Blockchain also lets medical records to be stored in protected, fragmented systems that can contain heaps of information. The tools allow providers to store a complete patient history and securely encrypt medical data. Moreover, providers can also build a private network for their blockchain and only invite patients directly.

Blockchain is Shared with Trusted Parties
When it comes to a telemedicine program, the blockchain will only be shared with a faithful patient and agreed upon by a party. When an accepted patient is added to the blockchain, their connected computer devices obtain a copy of the blockchain. The sheet is updated whenever a new block of transactions is appended. Furthermore, only someone with the private key could access the electronic protected health data in the blockchain. On the whole, the process makes the private blockchain network almost invulnerable.
In its application to telemedicine, blockchain will help form a seamless exchange of information and increase consumer assurance in the system. In such an arrangement, the data entered into a PC must be approved by the patient and doctor and verified against a previous ledger. Both the doctor and patient can secure a personal copy of the ledger, rather than a single party having control over the data. The method ensures that multiple checks are in place for protecting sensitive information, reducing some of the telemedicine’s primary security concerns.
Healthcare providers can leverage blockchain to firmly store patient’s Electronic Protected Health Information (ePHI). When a medical record is generated and signed, it can be written into the blockchain that provides patients with the proof and self-reliance that the file cannot be changed. The occurrence will also provide nonrepudiation, an assurance that someone cannot deny altering the medical record. Additionally, the process also stores the authenticity of their signature on paper and, finally, the legitimacy of a message they sent.
Blockchain is Protected by Private Keys
The personal health records could be programmed and stored on the blockchain with a private key so that they are only accessible by pre-approved individuals, thus ensuring privacy. The major hurdles in adopting blockchain in telemedicine include the cost, lack of standardization, and lack of proficiency in the industry of how to implement it.
The cost of implementing the technology and broadening participation to lower supply tiers is a worry because blockchain technology relies on intensive computing power. Therefore, the process requires a lot of electricity to operate. The approach might be particularly difficult for patients in rural areas due to a lack of resources and infrastructure.
The lack of expertise for providers, patients, and even some IT professionals is also an obstacle. The hurdle may be challenging to overcome when coupled with the problem that blockchain is expensive to operate. Another problem is the lack of interoperability or standardization, which limits the capability for platforms to connect.
