Definition of Fraud: Noun

"1. Wrongful deception with the intent to gain personally or financially.

2. Intentional deception in order to persuade another person to part with something of value.

3. A person who pretends to be something or someone he is not."

Not to mention the impact that fraud can bring to a company. If you see the types of fraud that is beautifully listed in the link here, It will be clear that a system with a central authority to control and manage will automatically render itself to fraud. Human involvement makes any system vulnerable and when topped with a central authority to process & validate. Fraud is more likely to be in systems where the linkage of products is across many industries.

Let me highlight a use case to explain my point. Let us say, Hafeez, own a famous restaurant that serves meat products that he promises is outsourced organically with no animal trafficking coming into the picture and no illegally sourced meat from unlicensed vendors. As he also promises that all the food products are hygienic and fresh. But to fulfill his promise and the serve the meat outsourced from vendors with confidence the following needs to be ensured in the supply of meat.

Say Jassi, animal farm owner along with 5 others vendors supply to Hafeez for different types of meat required in his restaurant. Before reaching restaurant the meats are transported to processing plants where they are processed and packed and also checked by the authority to verify & certify that it is from legal farm & condition of it is safe to be processed and delivered in the market. In all this process the temperature is a parameter which should be constantly maintained and logged at each step so that the meat is safe to consume.

The above example of a supply chain problem is prone to fraud at many stages. Starting from the first step, the meat can be given to processing plant from unregistered slaughterhouse or animal farm. Well, a smart contract enabled from blockchain technology will be of good use here. Here a smart contract can be made so that it records some necessary details about the meat supplier like name, business id & meat quantity and temperature stored at before leaving the animal farm. This data is checked with the contract conditions and if the supplier is like Jassi who is certified business, then the transaction is recorded on blockchain network.

Now let's say a Logistics company is involved in providing pickup and drop meat from producer to processing plant. Here the main pain point is to ensure that the meats are always under maximum allowed temperature so that it is not spoilt. Traditional IOT technology does help us to monitor temperature, track delivery real-time, but trust is an issue here as logistics companies can tamper with data before pushing it to customers. A blockchain enabled network will not only ensure transparency as it is peer to peer network, the data points created while in transit will be immutable too. Also, an app on Hafeez end can be made to check the delivery details and all notifications/information regarding the shipment. These data will be accessible to authorized people involved in each stage of supply chain and will be auditable.

The above example can be extended to further our discussion. Now processed meat which is packed will bear some information like date and serial number, preservatives used, best before and storing condition specification. Again immutability, transparency which makes data auditable increase trust in the system.  

At the end of the supply chain when meat is received by Hafeez, he being part of the network, he can trace the provenance of the meat and be confident while serving it.

From the above classic problem of the supply chain, It is clear that blockchain provides a trustable, fast, auditable and immutable system that is more resistant to fraud and even if fraud occurs, it gives easy traceability of culprit.

The above example can be replaced with many use case scenarios:

1) Cultivation of Opium for Medical industry and pharmaceutical industry.

2) Exam conduction in a transparent way.

3) Traceability and credibility of diamonds & related gemstone industry.

4) Tenders and process of awarding the contract through blockchain.

5) Judicial proceedings using Distributed ledger technology.

6) Ownership and transfer of assets like cars, land, even cash (fiat currency).

Well, the list is endless and you can cite your favorite use case not mentioned here in comments.Basically, all the processes where people are involved, and central authority to keep a check, fraud is rampant, due to a slow paper-based system and very hard to audit and even when audited and a case of fraud is detected, proving the culprit is very tricky. These inherent drawbacks of the traditional system & corresponding advantages of Blockchain make it defacto system of future in every field where forgery is a big problem.

Photoshop is one of the most powerful applications around. When it comes to working with photos, there’s almost nothing it can’t do. Even the name “Photoshop” is a byword for image editing.

Since it launched more than 25 years ago, however, Photoshop’s picked up loads of new features that let it do even more. Adobe has developed the Creative Cloud into a suite of overlapping apps. Some of the tools from programs like Illustrator have made their way into Photoshop and vice versa. Photoshop can now do a lot more than just edit photos.

Let’s look at some of the ways you can make use of my favorite program, Photoshop.

1. Editing Photos:

Editing Photos is Photoshop’s original use, it’s in the name after all. Even after a quarter of a century of competition, Photoshop is the most powerful image editor out there. You can modify any pixel in an image pretty much any way you’d like.

  • If you just want to enhance the colors, add some contrast, or crop the image, you can.

  • If you want to do a full magazine style retouch, you can.

  • If you want to make an old photo from your grandparents’ wedding look like it was printed yesterday, you can.

  • If you want to create a photo of you being hit on the head with a hammer by a killer doll, you can.

Basically, if there’s any conceivable way to edit an image, you can do it with Photoshop. It’s used by tens of thousands of people every day. There might be some competitors out there but it’s still the industry standard and no app really beats it on features. Photoshop, first and foremost, is always going to be an image editor.

2. Digital Painting:

Most paintings, cartoons, book covers, and other art that you see online isn’t created with a paintbrush, paints, and a canvas. It might not look like it but most of them are now “painted” using a computer. Photoshop is one of the most popular apps for doing just that.

Digital painting uses technology to emulate old school, brush-in-hand, beret-on-head painting. With a Waccom graphics tablet you can draw or paint without having to use a mouse, or god-forbid, a touchpad. This means you can work with a far more natural tool for the job. When you paint, different colors will combine to create new colors just as you’d expect acrylics or oils to do. You can get the effects of everything from a felt marker to a can of spray paint all while staying within Photoshop. There’s a reason so many artists use it over more analog tools.

Creating digital art has a steeper learning curve than editing photos. Luckily, Christian’s put together this great list of Digital Art courses if you want somewhere to get started.

3. Graphic Design:

Although Adobe also has graphic design specific apps like InDesign and Illustrator in the Creative Cloud, many of their tools have been incorporated into Photoshop as well. For example, the Pen Tool is a staple in almost all Adobe’s apps.

While Photoshop isn’t the best graphic design app out there, it is entirely competent. Something more specialized will make your life easier but there is very little you can’t do. If you’re going to do regular design work, investing time in learning one of the other apps is worth it, but if you just occasionally want to create a Christmas card, design your t-shirt, mock up a quick logo for your business, or even create a business card, Photoshop is perfect.

4. Web Design:

One of the most important steps in web design is creating a mock up: a finished design made in an app like Photoshop. It’s something that amateurs often skip. I know that when I first started designing websites, I jumped straight into coding rather than taking the time to plan out what I wanted the site to really look like. All I had was a rough vision in my head.

As you can imagine, this led to all sorts of problems. Designs took a huge amount of tweaking and going back and forth to make things look right. I’d spend an hour changing something with code that would take 30 seconds in Photoshop.

There’s a reason professional web designers start in Photoshop. It’s far easier to resize objects, move things around the page, and just try ideas out. Once you start working with HTML, one tiny tweak can start breaking all the work you’d done before. Anyone planning to design a website should start in Photoshop.

5. Editing Video:

This last use might be a surprise to you but it’s entirely possible to edit video in Photoshop. You’re not going to cut together a Hollywood blockbuster, or even a short film, but for editing small clips it can be really convenient.

The best thing about editing videos in Photoshop is that you get to use adjustment layers just as if you were editing a photo. If you want to convert a regular video you shot on your iPhone into a high contrast, black and white, film noir style clip, you can do it with just three layers.

If you know how to edit photos but don’t know how to use apps like Premiere Pro and After Effects, Photoshop can be a great alternative. All the tools you’re familiar with are there. Another awesome feature of using Photoshop to edit videos is you can also create GIFs!

6. Whatever You Want:

Photoshop is an incredible app with an awesome array of tools. While it was originally meant for editing photos, it can do a whole lot more. In fact, there’s almost nothing you can’t do. It might be a bit time consuming but if you wanted to create a spreadsheet or write an essay, you could actually do it with Photoshop’s tools.
