SCIN Dataset

The SCIN (Skin Condition Image Network) open access dataset aims to supplement publicly available dermatology datasets from health system sources with representative images from internet users. To this end, the SCIN dataset was collected from Google Search users in the United States through a voluntary, consented image donation application. The SCIN dataset is intended for health education and research, and to increase the diversity of dermatology images available for public use.

The SCIN dataset contains 5,000+ volunteer contributions (10,000+ images) of common dermatology conditions. Contributions include Images, self-reported demographic, history, and symptom information, and self-reported Fitzpatrick skin type (sFST). In addition, dermatologist labels of the skin condition and estimated Fitzpatrick skin type (eFST) and layperson estimated Monk Skin tone (eMST) labels are provided for each contribution.

Please note: This dataset contains images of medical conditions, some of which may be sensitive and/or graphic in nature.

Section 2 -- Scope.

a. License grant.

   1. Subject to the terms and conditions of this SCIN License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable (except as set forth herein), non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:

        a. reproduce and Share the Licensed Material, in whole or in part; and

        b. produce, reproduce, and Share Adapted Material.

   4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this SCIN License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

   5. Downstream recipients.

        b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material and/or any Adapted Materials if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material and/or any Adapted Materials.

   6. No endorsement. Nothing in this SCIN License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

   1. Moral rights, such as the right of integrity, are not licensed under this SCIN License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

   2. Patent and trademark rights are not licensed under this SCIN License.

   3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

b. Restrictions: You may not make any attempt to re-identify or re-link any of the individual data subjects whose data has been de-identified to create the Licensed Materials. Re-identification or re-linking of any such individual subjects is strictly prohibited and results in the immediate termination of all rights granted to the Licensed Materials and/or any Adapted Materials.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material and/or Adapted Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this SCIN License where the Licensed Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This SCIN License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this SCIN License, then Your rights under this SCIN License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

   1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

   2. upon express reinstatement by the Licensor.

 For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this SCIN License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this SCIN License.

b. To the extent possible, if any provision of this SCIN License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this SCIN License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this SCIN License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this SCIN License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
