A method of ensuring privacy through data federation in an Internet-of-Things (IoT) system involves receiving the data message; determining whether the data message is containing new information; and if so, based on the determination that the data message contains the latest information, selecting one or more directives to trigger based upon the data message, and then generating an registration based on one or more triggered directives.

In the past 10 years over the past decade, the Internet-of-Things (IoT) concept has been adopted overwhelmingly across a variety of fields that produce data and processed (e.g. healthcare, automotive smart cities, industrial and so on.) This has resulted in a variety of IoT platforms and IoT deployments.

As an example for instance, the IoT concept is being used in the healthcare industry where sensitive data is and of most crucial importance to save lives. Today, many medical devices rely on heterogeneous sensors. They are used, for in the home for instance, for monitoring patients and promptly delivering hints and alerts that are timely, or for having an offline data analysis discovering patterns, anomalies, and similar. The gateway is accountable for data security, exposure and reporting to other platforms. It can also handle reports and provide data to other domains, such as cardiology, nutrition, and nutrition. Different administrations are able to control the sensors. Medical applications that use big data may require data input from multiple domains for computing accurate output. Additionally the quality of the data should be very high so only sensors or gateways that are allowed to be allowed to push certain parameters.

Another typical IoT use-case is Smart Cities. In Smart Cities the sensors are installed almost everywhere in the public space and controlled by various different parties. For instance, there might be sensors for tracking buses (e.g. that measure speed, acceleration or location) that are owned by the public transportation industry or surveillance cameras managed by homeland security as well as crowdsourced data collected from an application for smartphones. A smart service for citizens could include dynamicallyoptimizing the public transportation services by scheduling bus arrival time and bus route based on current needs (e.g., serving crowds moving within the city), or enhancing the transportation capabilities by supplementing the basic schedule with extrabus/tram rides as needed. To achieve this crowd detection data gathered from bus stop cameras, crowd mobility patterns from smartphone applications, and the utilization of fleet capacity could be used to inform an online analysis. A third-party company that provides such services (for example an academic research lab or an entrepreneur) may not know who is storing and providing the information. Thus, the third-party must be able to discover information availability on its own. The quality of the services may improve if volume or quality of data increases.

Smart Industry is another IoT application. Manufacturing companies for machinery are creating devices that are equipped with sensors to monitor life-cycle and operational behaviors. Industries typically employ equipment made by several machinerycompanies with each of them offering their own data services as well as specialized equipment. If data from the majority or all producers is shared, some software that improve production and enhance security in factories are possible. However, machinery companies are able to protect their personal data and would like to protect their data.

It has taken considerable effort to create standards and ontologies to facilitate interoperability among platforms and inter-domain interactions. There are three options for centralizing platforms and data storage under one authority, A Federation of Platforms that leaves the sovereignty to the local IoT administrator or a mixture of both centralization and the federation approach. A federation-based approach is typically more desirable to agencies who are hesitant (or areby regulation not permitted) to give up control of data (e.g. smart homes as well as public administration and industrial facilities). In fact, currently various IoT platforms are in operation and locally managed with IoT applicationsbuilt on top creating isolated domain silos.

A method of privacy-preserving data federation in an internet-of?things (IoT) in accordance with the invention, is described in detail. It involves: receiving an email, determining if it contains new information, based upon that determination, determining the appropriate directives on which to be triggered based on the data messages; and then creating a registration using the one or more triggered instructions.

What is a patent?

Patents are granted by the government to protect the invention. It grants the inventor the sole right to create, use and sell the invention. Society gains when new technologies are brought for sale. The benefits may be the direct sense, since it allows individuals to achieve previously impossible things, or indirectly due to the opportunities for economic growth (business growth and employment) which the invention provides.

Many pharmaceutical companies and university researchers seek protection under patents for their work and research. Patents may cover an abstract or physical product or process, or even a method or composition of materials unique to the area. Patent protection is granted to any invention that is valuable unique, innovative, and not previously known to others in the same area.

Patents are awarded to inventors who have commercially successful inventions. They serve as a motivator for inventors to invent. Patents allow entrepreneurs and inventors to be confident that there’s the possibility that they’ll be paid back for their time, effort, and money invested in the development of technology. It means that they can earn a living from their work.

Companies that are able to:

Protect your innovative products and services.

Increase the visibility and value of your products ‘ presence on the market

Differentiate your business and products from the rest;

Access technical and business knowledge and other information;

Avoid the risk of accidentally using third-party proprietary content or losing valuable data, original outputs, or any other innovative output.

Patents convert knowledge of the inventor into an asset that can be sold, which creates new opportunities to create jobs through licensing and joint ventures.

Investors in the development and commercialization of technology will appreciate small companies with patent protection appealing.

Patenting can lead to new ideas and inventions. This information can promote innovation and may qualify for protection under patents.

Patents can serve as an obstacle to unscrupulous third parties that profit from the efforts of an invention.

Patent-protected technology that is commercially viable can be used for financing technology-related research and development (R&D), which will improve the chances for better technology in the future.

Intellectual property ownership can be used to convince lenders and investors that there are genuine opportunities to commercialize your product. One powerful patent may open the door for many financing opportunities. You can utilize patents and other IP assets as collateral or security to secure financing. Investors may also look at your patent assets to boost the value of their company. Forbes and others have stated that each patent could increase company valuation by anywhere from $500,000 to $1 million.

A well-designed business plan is vital for startups. It should be based on IP and explain how your product/service is distinctive. Investors will be impressed if you have IP rights are secured or are in the process of being secured, and they are in line with your business plan.

It is crucial to protect an invention before applying for patent protection. A public divulging an invention could be detrimental to its novelty and make it invalid. Pre-filing disclosures, such as for investors, test marketing, or other business partners should be done only after signing a confidentiality contract.

There are many kinds of patents. Understanding these is vital to safeguard your invention. Patents on utility cover inventions and processes that are new. Design patents cover ornamental designs. Utility patents are the best as they protect the proprietor from copycats and other competitors. In most cases, utility patents are issued for improvements or modifications to existing inventions. Utility patents also cover enhancements and modifications to existing inventions. For instance, a process patent covers acts or methods of doing one specific thing, whereas chemical compositions are an assortment of components.

How long will a patent last? Although utility patents are valid for 20 years from the date of their earliest filing, they can be extended through delay at the Patent Office.

Alongside the USPTO search engine, you can also utilize other search engines such as espacenet, as detailed below. Patent lawyers or a patent attorney can advise you on the process. Patents granted in the United States are granted by the US trademark and patent office as well as the United States patent office. This office also reviews trademark applications.

Are you interested in finding similar patents? Here are the steps to follow:

1. Create a list of terms that describe your invention based on its purpose, composition, and usage.

Write down a brief detailed explanation of your invention. Avoid using generic terms like “device,” “process,” and “system.” Look for synonyms to the terms you initially chose. Next, take note of crucial technical terms as well as keywords.

To help you identify keywords and concepts, use the following questions.

  • What is the objective of the invention Is it a utilitarian device or an ornamental design?
  • Does the invention consist of a method of making something or performing some function? Is it a product or procedure?
  • What is the composition and function of the invention? What is the physical makeup of the invention?
  • What’s the point of the invention
  • What are the technical terms and phrases that define the nature of an invention? A technical dictionary can help you locate the right words.

2. Utilize these terms to locate pertinent Cooperative Patent Classifications for your invention at the Classification Text Search Tool. To determine the best classification to your invention, go through the class scheme of the classification (class schedules). If you don’t get any results using the Classification Text Search, you might consider substituting your words for describing your invention with synonyms.

3. Go through the CPC Classification Definition to verify the accuracy of the CPC classification you’ve discovered. If the selected classification title is a blue box that has the letter “D” at its left, clicking on the link will direct you to the CPC classification description. CPC classification definitions can help identify the specific classification’s scope, so you are sure to select the most appropriate. Additionally they can provide research tips and other suggestions that could be useful for further research.

4. Retrieve patent documents with the CPC classification from the Patents Full-Text and Image Database. You can review and narrow down the relevant patent publications looking first at abstract and drawings representative of.

5. This selection of patent publication is the best to examine for similarity to your idea. Pay attention to the claims and specification. There are many patents available by consulting the patent examiner and applicant.

6. Retrieve published patent applications with the CPC classification you chose in Step 3 in the Applications Full-Text and Image Database. You can use the same method of search in Step 4 to narrow your search results down to the most relevant patent applications by examining the abstract and drawings that appear on each page. The next step is to review all published patent applications carefully with particular attention paid to the claims as well as other drawings.

7. You can find additional US patent publications by keyword searches in AppFT or PatFT databases, and also classification search for non-U.S. Patents as described below. You can also make use of search engines on the internet to search for non-patent-related documents that describe inventions in the literature. Examples:

  • Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
  • Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
  • Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.

To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
